kernel OoPs after updating to 2.6.20-1.2933.fc6xen
by Asrai khn 03 May '07

03 May '07

Hi, Today after updating kernel-xen to 2.6.20-1.2933.fc6xen on one of our host I got kernel oops and machine rebooted, when it come back again i have no other choice but to edit grub.conf and make the last working kernel ' 2.6.19-1.2911.6.5.fc6xen' the default one which working fine. DemU(s) working fine with with same kernel 2.6.20-1.2933.fc6xen, we use loopback mounted fs for domU(s) Here are the messages i found on screen before machine got rebooted (Note: machine is remote to me thousands of miles away therefore i can't check its boot screen :-S ) Now I am reluctant to update kernel-xen on our other remote hosts, never got into such issue on FC6 while updated kernel-xen. In help/suggestion will be greatly appreciated. ------ [root@xxxxx ~]# Message from syslogd@xxxxx at Mon Mar 26 20:17:02 2007 ... xxxxx kernel: Oops: 0003 [#1] Message from syslogd@xxxxx at Mon Mar 26 20:17:02 2007 ... xxxxx kernel: SMP Message from syslogd@xxxxx at Mon Mar 26 20:17:02 2007 ... xxxxx kernel: CPU: 0 Message from syslogd@xxxxx at Mon Mar 26 20:17:02 2007 ... xxxxx kernel: EIP: 0061:[<c0548ceb>] Not tainted VLI Message from syslogd@xxxxx at Mon Mar 26 20:17:02 2007 ... xxxxx kernel: EFLAGS: 00010017 (2.6.20-1.2933.fc6xen #1) Message from syslogd@xxxxx at Mon Mar 26 20:17:02 2007 ... xxxxx kernel: EIP is at evtchn_do_upcall+0x55/0x97 Message from syslogd@xxxxx at Mon Mar 26 20:17:02 2007 ... xxxxx kernel: eax: 00000010 ebx: 00000000 ecx: eaa35fe4 edx: ffffffec Message from syslogd@xxxxx at Mon Mar 26 20:17:02 2007 ... xxxxx kernel: esi: 00000001 edi: f5416000 ebp: fffffffe esp: eaa35fc4 Message from syslogd@xxxxx at Mon Mar 26 20:17:02 2007 ... xxxxx kernel: ds: 007b es: 007b ss: 0069 Message from syslogd@xxxxx at Mon Mar 26 20:17:02 2007 ... xxxxx kernel: Process find (pid: 4000, ti=eaa35000 task=ed7b12f0 task.ti=eaa35000) Message from syslogd@xxxxx at Mon Mar 26 20:17:03 2007 ... xxxxx kernel: Stack: 00000000 00000000 00000003 eaa35fac eaa35fe4 eaa35000 c0404ff2 eaa35fe4 Message from syslogd@xxxxx at Mon Mar 26 20:17:03 2007 ... xxxxx kernel: b7ff0402 00000073 00000212 bf93c920 0000007b 00000000 00000000 Message from syslogd@xxxxx at Mon Mar 26 20:17:03 2007 ... xxxxx kernel: Call Trace: Message from syslogd@xxxxx at Mon Mar 26 20:17:03 2007 ... xxxxx kernel: ======================= Message from syslogd@xxxxx at Mon Mar 26 20:17:03 2007 ... xxxxx kernel: [<c0404ff2>] hypervisor_callback+0x46/0x50 Message from syslogd@xxxxx at Mon Mar 26 20:17:03 2007 ... xxxxx kernel: Code: bd fe ff ff ff 88 d9 89 d8 c1 e0 05 d3 c5 89 04 24 eb 29 0f bc c0 03 04 24 8b 14 85 80 f0 6f c0 83 fa ff 74 12 8b 4c 24 1c f7 d2 <89> 51 28 89 c8 e8 16 db eb ff eb 05 e8 22 2e 00 00 8b 44 24 04 Message from syslogd@xxxxx at Mon Mar 26 20:17:03 2007 ... xxxxx kernel: EIP: [<c0548ceb>] evtchn_do_upcall+0x55/0x97 SS:ESP 0069:eaa35fc4 Read from remote host xxxxx.xxxx.com: Connection reset by peer Connection to xxxxx.xxxx.com closed.

by pradeep ratnala 04 Apr '07

04 Apr '07

Hi I am trying to build a xen aware guest kernel ....I have 2.6.16 as the host kernel over which I built a fc5-xen kernel..Now I am trying to build a custom xen aware kernel over this. Can someone help me in this...Is there any step by step procedure for doing this?...To my knowledge I may have to remove all the direct hardware driver links in the custom kernel.... Thanx Pradeep

Hello, Is it possible to setup a guest OS using an existing installation of a given OS ? I only seem to find references for creating guests via a fresh install of the guest OS ? Thanks! P.S. Please, CC me since I am not subscribed to the list.

Xen network problem
by Daniel 30 Mar '07

30 Mar '07

Hi I have a Fedora Core 6 Xen box running two Linux hosts and one Windows Server 2003 host. I am having trouble with the Windows VM network. It was working fine but for some reason it has decided to stop. I can not ping the Windows VM for Domain-0 and I can not ping out from the Windows VM. The Windows VM has and detects the network interfaces no problem. The Windows VM network did work fine but stop for some strange reason. Both Linux hosts work fine. Each VM has two vif. Both don't work in the problem VM. It is the last VM to be started on boot. The other two VMs have two vif each as well. vif0 is bound to eth0 and vif1 is bound to eth1. I notice this machine has only 8 loop devs could this be the problem? Any help greatly appreciated as I am stumped. xen-3.0.3-8.fc6 xen-libs-3.0.3-8.fc6 kernel-xen-2.6.20-1.2933.fc6 I get this in dmesg which I guess is my problem: device vif5.0 entered promiscuous mode ADDRCONF(NETDEV_UP): vif5.0: link is not ready device vif5.1 entered promiscuous mode ADDRCONF(NETDEV_UP): vif5.1: link is not ready Regards Daniel dir /dev/loop* brw-r----- 1 root disk 7, 0 Mar 26 20:10 /dev/loop0 brw-r----- 1 root disk 7, 1 Mar 26 20:10 /dev/loop1 brw-r----- 1 root disk 7, 2 Mar 26 20:10 /dev/loop2 brw-r----- 1 root disk 7, 3 Mar 26 20:10 /dev/loop3 brw-r----- 1 root disk 7, 4 Mar 26 20:10 /dev/loop4 brw-r----- 1 root disk 7, 5 Mar 26 20:10 /dev/loop5 brw-r----- 1 root disk 7, 6 Mar 26 20:10 /dev/loop6 brw-r----- 1 root disk 7, 7 Mar 26 20:10 /dev/loop7 The xen log: [2007-03-31 10:03:44 xend.XendDomainInfo 3301] DEBUG (XendDomainInfo:190) XendDomainInfo.create(['vm', ['name', 'w2k3R2-test-002'], ['memory', 768], ['shadow_memory', 8], ['on_reboot', 'restart'], ['on_crash', 'restart'], ['vcpus', 1], ['image', ['hvm', ['kernel', '/usr/lib/xen/boot/hvmloader'], ['device_model', '/usr/lib64/xen/bin/qemu-dm'], ['vcpus', 1], ['boot', 'c'], ['vnc', 1], ['vncunused', 1], ['xauthority', '/root/.Xauthority'], ['vncpasswd', None]]], ['device', ['vbd', ['uname', 'file:/home/vm/w2k3/w2k3R2-test-002.img'], ['dev', 'ioemu:hda'], ['mode', 'w']]], ['device', ['vif', ['bridge', 'xenbr0'], ['type', 'ioemu']]], ['device', ['vif', ['bridge', 'xenbr1'], ['type', 'ioemu']]]]) [2007-03-31 10:03:44 xend.XendDomainInfo 3301] DEBUG (XendDomainInfo:296) parseConfig: config is ['vm', ['name', 'w2k3R2-test-002'], ['memory', 768], ['shadow_memory', 8], ['on_reboot', 'restart'], ['on_crash', 'restart'], ['vcpus', 1], ['image', ['hvm', ['kernel', '/usr/lib/xen/boot/hvmloader'], ['device_model', '/usr/lib64/xen/bin/qemu-dm'], ['vcpus', 1], ['boot', 'c'], ['vnc', 1], ['vncunused', 1], ['xauthority', '/root/.Xauthority'], ['vncpasswd', None]]], ['device', ['vbd', ['uname', 'file:/home/vm/w2k3/w2k3R2-test-002.img'], ['dev', 'ioemu:hda'], ['mode', 'w']]], ['device', ['vif', ['bridge', 'xenbr0'], ['type', 'ioemu']]], ['device', ['vif', ['bridge', 'xenbr1'], ['type', 'ioemu']]]] [2007-03-31 10:03:44 xend.XendDomainInfo 3301] DEBUG (XendDomainInfo:397) parseConfig: result is {'shadow_memory': 8, 'start_time': None, 'uuid': None, 'on_crash': 'restart', 'on_reboot': 'restart', 'localtime': None, 'image': ['hvm', ['kernel', '/usr/lib/xen/boot/hvmloader'], ['device_model', '/usr/lib64/xen/bin/qemu-dm'], ['vcpus', 1], ['boot', 'c'], ['vnc', 1], ['vncunused', 1], ['xauthority', '/root/.Xauthority'], ['vncpasswd', None]], 'on_poweroff': None, 'bootloader_args': None, 'cpus': None, 'name': 'w2k3R2-test-002', 'backend': [], 'vcpus': 1, 'cpu_weight': None, 'features': None, 'vcpu_avail': None, 'memory': 768, 'device': [('vbd', ['vbd', ['uname', 'file:/home/vm/w2k3/w2k3R2-test-002.img'], ['dev', 'ioemu:hda'], ['mode', 'w']]), ('vif', ['vif', ['bridge', 'xenbr0'], ['type', 'ioemu']]), ('vif', ['vif', ['bridge', 'xenbr1'], ['type', 'ioemu']])], 'bootloader': None, 'cpu': None, 'maxmem': None} [2007-03-31 10:03:44 xend.XendDomainInfo 3301] DEBUG (XendDomainInfo:1264) XendDomainInfo.construct: None [2007-03-31 10:03:44 xend.XendDomainInfo 3301] DEBUG (XendDomainInfo:1296) XendDomainInfo.initDomain: 5 1.0 [2007-03-31 10:03:44 xend 3301] DEBUG (image:329) args: boot, val: c [2007-03-31 10:03:44 xend 3301] DEBUG (image:329) args: fda, val: None [2007-03-31 10:03:44 xend 3301] DEBUG (image:329) args: fdb, val: None [2007-03-31 10:03:44 xend 3301] DEBUG (image:329) args: soundhw, val: None [2007-03-31 10:03:44 xend 3301] DEBUG (image:329) args: localtime, val: None [2007-03-31 10:03:44 xend 3301] DEBUG (image:329) args: serial, val: None [2007-03-31 10:03:44 xend 3301] DEBUG (image:329) args: std-vga, val: None [2007-03-31 10:03:44 xend 3301] DEBUG (image:329) args: isa, val: None [2007-03-31 10:03:44 xend 3301] DEBUG (image:329) args: vcpus, val: 1 [2007-03-31 10:03:44 xend 3301] DEBUG (image:329) args: acpi, val: None [2007-03-31 10:03:44 xend 3301] DEBUG (image:329) args: usb, val: None [2007-03-31 10:03:44 xend 3301] DEBUG (image:329) args: usbdevice, val: None [2007-03-31 10:03:44 xend 3301] DEBUG (image:329) args: k, val: None [2007-03-31 10:03:44 xend 3301] DEBUG (balloon:127) Balloon: 810284 KiB free; need 808756; done.

Createing/working with disk images
by Lamont R. Peterson 30 Mar '07

30 Mar '07

All, I need to create some images that pygrub can boot (on FC6 & RHEL5). IIUC, that means that the image file must be a disk image complete with partition table. The trouble I'm running into is figuring out how to access the "partition" within the disk image file as a block device. This is necessary in order to format or mount the filesystems and run mkswap for the disk image's swap partition. Here's what I have so far. 1. Create the disk image file, ala "dd if=/dev/zero of=/var/lib/xen/images/someVM/sda bs=1k seek=4608k count=1" 2. Create partitions with fdisk (this requires setting the number of cylinders, but that's easy). 3. losetup /dev/loop0 /var/lib/xen/images/someVM/sda At this point, I can run "fdisk -l /dev/loop0" and get: Disk /dev/loop0: 4831 MB, 4831839232 bytes 255 heads, 63 sectors/track, 587 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/loop0p1 1 523 4200966 83 Linux /dev/loop0p2 524 588 522112+ 82 Linux swap / Solaris However, there is no /dev/loop0p1 or /dev/loop0p2 devices and I'm not sure what to do to make those accessible. I need to be able to "mke2fs -j /dev/loop0p1" and "mkswap /dev/loop0p2" or equivalent. Then I need to mount /dev/loop0p1 to copy files to it. How can I access partitions inside a disk image as block devices? Should I be using something other than losetup here? -- Lamont Peterson <lamont(a)gurulabs.com> Senior Instructor Guru Labs, L.C.

Re: [et-mgmt-tools] what happen? :(

Hi Michael, i'm sending your response to fedora-xen mailing list for any comments from them. About your answer, the machine where i want to create a new virtual node is the 136.145.116.76. This machine has two virtual nodes up and running, so i think that message is not a hypervisor problem, the hypervisor is working. The other hand, last week i create two additional virtual nodes, in that machine (116.76), the problem appear today. Asides, the distro and profile configuration keep the same. I can't understand why today, provisioning with cobbler stop to work.

Windows XP install failed on FC6-Xen
by NoisilySilent 30 Mar '07

30 Mar '07

Hi, Installation hangs after first reboot during Windows XP installation procedure. System first boots from CD as expected, formats an NTFS file system, copies installation files, reboots and . hangs. Looking at the log, I had a "vncpasswd error" => created a vncpasswd and got rid of this error message. Now, no error is logged, but still I get a blank screen whenever I try to "xm create" this Windows host. System is a Dell Latitude D620 notebook, Intel Core2 Duo processor, FC6 downloaded last week, Xen installed via YUM, so I don't know exactly which version yum installs, 3.?.? Anybody got clues, as I didn't find anything through google search? Cheers

Hi list! Any information about this bug: https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=234008 It seems to affect many people.. latest 2.6.19 kernel-xen runs fine on the same hardware/dom0.. but 2.6.20 crashes/freezes quite immediately. -- Pasi

installing winxp on rhel5
by Deependra Singh Shekhawat 28 Mar '07

Hello guys, I have RHEL5. I want to install Windows XP on it using Xen. I heard I need PAE enabled processor. So I did the following: [root@server ~]# grep -i pae /proc/cpuinfo And I got this: flags : fpu tsc msr pae mce cx8 apic mtrr mca cmov pat clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe nx constant_tsc pni monitor vmx est tm2 xtpr flags : fpu tsc msr pae mce cx8 apic mtrr mca cmov pat clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe nx constant_tsc up pni monitor vmx est tm2 xtpr [root@server ~]# Does this tells that I have PAE enabled processor. One more thing I have 512 MB RAM (physical total RAM). So how much should I give to the Virtual Machine and last thing the installation source in this case can be a CD or ISO image. Thanks in advance Regards Deependra -- Enjoy Life !
