initscripts, xen and bonding
by Axel Thimm 04 Mar '07

04 Mar '07

Hi, I'm having a hard time getting bonding to work on FC5t3. It looks like the bond0 interface bond0 is renamed to pbond0 by xen [*] and the enslaving does not work anymore then. It works if I log on the terminal and ifenslave the devices to pbond0 instead of bond0 after the boot process has finished. But I want this to be handled automatically during reboots, so I tried assigning the bonding slaves to pbond0 as a master in the ifcfg-eth{0,1} scripts, but that doesn't work. What is causing the bond0 rename and should this renaming be considered by initscript? Is this a user error or should I file this against bugzilla? xen or initscripts? Thanks! [*] The only reference I found was a Japanese site and google's translation of it. http://translate.google.com/translate?hl=en&sl=ja&u=http://hoop.euqset.org/… -- Axel.Thimm at ATrpms.net

Simple testing results for Xen and VMX on FC5-test2.
by You, Yongkang 12 Jan '07

12 Jan '07

Hi all, I have done a simple checking for Xen and VMX on FC5-test2. Basically, I can create VMX on FC5-test2 IA32. But FC5-test2 IA32e (x86-64) doesn't provide Xen and Xen0 kernel, so didn't do Xen and VMX testing for it. Beside of testing Xen and VMX, I also found some issues about installation, which I have updated the bug #179078 as a NB. The following is the testing results only for Xen and VMX. ========================= 1. *** IA32E hasn't RPMS about Xen hypervisor and Xen0/XenU kernels. __FAIL__ 2. *** In order to boot up IA32 Xen0, I have to add pci=noacpi as the boot parameters of Xen0 kernel, or system will hang when initial PCI. I don't know if it is only related to my Machine. __FAIL__ 3. After install IA32 Xen RPMs, I can see /boot/grub/grub.conf has been changed with Xen kernels. __PASS__ 4. *** /usr/lib/xen/boot/vmxloader isn't in the RPM package, so VMX Guest couldn't be created. I suspected build system hasn't bcc, it is from DEV86 package. __FAIL__ 5. After copy a useable vmxloader to the destination, IA32 VMX Guest can be created successfully! __PASS__ 6. VMX has good network connection and Xwindows started. __PASS__ 7. XenU can be created and works well. __PASS__ 8. Couldn't get Xen Changeset by "xm info" or "xm dmesg". 9. The new kernel names of Xen/Xen0/XenU seemed a little confused. E.g. the Xen0 name is like vmlinuz-2.6.15-1.29_FC5hypervisor. I thought hypervisor is for Xen.gz. Xen0 is the Service OS. ========================== Any comments please let me know. But I will have 8 days holiday from tomorrow, so emails reply might be slow and occasional. [FYI] We are planning to do more testing for FC5-test3. Best Regards, Yongkang (Kangkang) 永康

Old serial mouse problem
by Philip Rhoades 27 Apr '06

27 Apr '06

People, I have been using a Logitech Serial Mouseman for some years quite happily on various RHx and now FC5 but I have to manually fix: /etc/sysconfig/mouse: FULLNAME="Generic - 3 Button Mouse (serial)" MOUSETYPE="Microsoft" XEMU3="no" XMOUSETYPE="Microsoft" IMOUSETYPE="ms" DEVICE=/dev/ttyS0 usually /etc/X11/x.org is OK with: Section "InputDevice" Identifier "Mouse0" Driver "mouse" Option "Protocol" "IMPS/2" Option "Device" "/dev/input/mice" Option "ZAxisMapping" "4 5" Option "Emulate3Buttons" "yes" EndSection but when I try and boot vmlinuz-2.6.16-1.2080_FC5xen0 I don't get a mouse . . How do I fix this? (short of upgrading to a PS2 mouse). Thanks, Phil. -- Philip Rhoades Pricom Pty Limited (ACN 003 252 275 ABN 91 003 252 275) GPO Box 3411 Sydney NSW 2001 Australia Mobile: +61:(0)411-185-652 Fax: +61:(0)2-8221-9599 E-mail: phil(a)pricom.com.au

How to expand the file created by xenguest-install?
by Denis Forveille 26 Apr '06

26 Apr '06

Does anyone has e detailed procedure to change the size (ie increase) of the file that is used as the "xvda" disk by a domU? This is the file created by the "xenguest-install" script (or the one created as in section 6.2 of the xen user's manual for the file-backed VBDs scenario). Thanks in advance

Xen Crash at Boot on Dell PE 830 Running FC 5
by Demetri Mouratis 26 Apr '06

26 Apr '06

[cross posted to xen-users(a)lists.xensource.com] Greetings, I'm having some trouble getting my new workstation, a Dell PE 830, up and running Xen on Fedora Core 5. The last step I see in the boot process is udev which completes with the standard [OK], then my monitor turns blank and looses any signal from my machine. If necessary, I could connect a serial port to get additional info on exactly where it is crashing. I'm using this machine as my desktop so I'd like to run X in the dom0 if possible. Please let me know if doing so is considered poor form with Xen. I've gone through the install process on an older Dell workstation successfully following the Fedora Xen Quickstart FC 5 guide here: http://fedoraproject.org/wiki/FedoraXenQuickstartFC5 The only way I've been able to work around this issue is to edit my /etc/inittab and set the default run level to 3 in which case the machine comes up clean. I've verified that selinux is disabled as I've seen some info to the effect that selinux and the nvidia drivers may have some issue. I'm hoping I can pass some argument at boot time to make this work or otherwise tweak something in the bios to get the xen kernel to boot and support X. Thanks in advance for any hints or tips. Here's the output of /proc/cpuinfo: processor : 0 vendor_id : GenuineIntel cpu family : 15 model : 4 model name : Intel(R) Pentium(R) 4 CPU 2.80GHz stepping : 9 cpu MHz : 2800.198 cache size : 1024 KB physical id : 0 siblings : 2 core id : 0 cpu cores : 1 fdiv_bug : no hlt_bug : no f00f_bug : no coma_bug : no fpu : yes fpu_exception : yes cpuid level : 5 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe nx lm constant_tsc pni monitor ds_cpl cid cx16 xtpr lahf_lm bogomips : 5606.72 processor : 1 vendor_id : GenuineIntel cpu family : 15 model : 4 model name : Intel(R) Pentium(R) 4 CPU 2.80GHz stepping : 9 cpu MHz : 2800.198 cache size : 1024 KB physical id : 0 siblings : 2 core id : 0 cpu cores : 1 fdiv_bug : no hlt_bug : no f00f_bug : no coma_bug : no fpu : yes fpu_exception : yes cpuid level : 5 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe nx lm constant_tsc pni monitor ds_cpl cid cx16 xtpr lahf_lm bogomips : 5600.31 And my grub.conf: # grub.conf generated by anaconda # # Note that you do not have to rerun grub after making changes to this file # NOTICE: You have a /boot partition.

RE: [Fedora-xen] File operation causes kernel panic
by Alex.Upton＠instinet.com 26 Apr '06

26 Apr '06

I recently experienced the same issue and noticed that it was related to my snmpd flipping out. I'm not sure if its just a buggy version of snmpd that ships with FC5 or if it's an overall issue with SNMPD and virtualized environments. Disabling snmpd resolved it for me, however I'm hoping this issue is resolved some day. Hope this helps. -Alex -----Original Message----- From: fedora-xen-bounces(a)redhat.com [mailto:fedora-xen-bounces@redhat.com] On Behalf Of EJacobsh(a)connectknowledge.com Sent: Wednesday, April 26, 2006 1:17 PM To: fedora-xen(a)redhat.com Subject: [Fedora-xen] File operation causes kernel panic Hello, I'm having a problem with a Dell server (PowerEdge 2850) and a recently installed Fedora Core 5 with Xen kernel (2.6.16-1.2096_FC5xen0).

File operation causes kernel panic

Hello, I'm having a problem with a Dell server (PowerEdge 2850) and a recently installed Fedora Core 5 with Xen kernel (2.6.16-1.2096_FC5xen0). Whenever I try to copy a larger file (128MB) to the server over the network, the server crashes (register dump on the console, remote sessions stop responding).
