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

can't boot xen kernel
by Justin Conover 04 Mar '06

04 Mar '06

I can't boot the kernel-xen-hypervisor on one of my systems. It bombs out when it wants to mount my /home Which is a RAID 5 with LVM, "can't find superblock", however a normal kernel boots fine. lsmod | egrep 'ata|raid' raid5 27585 1 xor 18249 1 raid5 raid1 24513 2 sata_sil 13641 4 libata 58189 1 sata_sil scsi_mod 129257 5 sg,aic7xxx,scsi_transport_spi,libata,sd_mod

minor Xorg screen corruption on radeon under xen dom0
by Andy Burns 02 Mar '06

02 Mar '06

I'm pleased to see xen for x86_64 recently :-) Under rawhide kernel 1955 with just a dom0 running I often see minor xorg screen corruption, usually showing as a series of solid/dashed red lines running across most of the top gnome-panel, this didn't happen when booted without xen. also if the machien was left for half a day or so it wouldn't wake ut of screen saver and needed CTRL-ALT-BKSP to kill/restart xorg. I've upgraded to kernel 1977 today and not seen it so far, and will bugzilla it if it happens again, just a quick "anyone else seen this" for now? I presume that any issue like this should be reported against xen not against xorg-drv-ati?

Request for comments: Xen on centrino thinkpads
by Kevin Verma 01 Mar '06

01 Mar '06

Hello, Some times ago, some where I had read that Xen does not work on centrino based thinkpads, is that still true ? I had tried to run xen on my thinkpad r50e having a centrino processor over FC4 but xen-hypervisor never booted succesfuly. I will be very much thankful for any of yours inputs to my questions above. Thanks for reading, Kevin

suse guest on fc5 host
by Darren Birkett 27 Feb '06

27 Feb '06

OK I'm probably missing something fairly important in my understanding, but I can't see how a guest for another OS can get installed/run on a different host system. I am currently experimenting on a test box, where I have the latest fc5t3 hypervisor kernel running, and 3 fc5t3 guests running. Installing and configuring these guests was easy with the xenguest-install.py script/anaconda. I want to try getting a SuSE 10 guest running under my fedora host system, but don't really know how. I know this is a fedora list but any pointers would be appreciated. I've seen the images downloadable from jailtime.org(not SuSE however), but where would I get the guest kernels for these images? Thanks Darren
