I remember reading that Xen gives only the first disk to pygrub as an arg. /usr/bin/pygrub is a Python script. Probably printing the 'file' var to stderr before the line fsimage.open(file, get_fs_offset(file)) shows what it's trying to open.

I think Fedora's on ext4 by default. One solution is to use ext2/ext3 for the domU's boot media or partition.

Re: [CentOS-virt] Fedora 12 2.6.31.5-127.fc12 domU on CentOS 5.4 2.6.18-164.6.1.el5xen fails to boot
I mentioned in a previous post that I specifically call out ext3 as the fstype option for /boot. To alleviate further confusion, here is my kickstart file. install cmdline url --url http://mirrors.rit.edu/fedora/linux/releases/12/Fedora/x86_64/os lang en_US.UTF-8 keyboard us network --device eth0 --bootproto dhcp rootpw ChangeMeNOW! firewall --enabled --port=22:tcp selinux --enforcing timezone --utc America/New_York bootloader --location=mbr reboot clearpart --all --initlabel part /boot --fstype=ext3 --size=256 part pv.01 --size=2048 --grow volgroup vg0 pv.01 logvol swap --fstype=swap --name=swap --vgname=vg0 --recommended logvol / --fstype=ext3 --name=root --vgname=vg0 --size=1024 --grow %packages --nobase If I simply change the url line to be fedora 11 instead of 12, everything works and I can boot. I decided to look into this a bit further. After installing and getting the following error: # pygrub /var/lib/xen/images/fedora12.img Traceback (most recent call last): File /usr/bin/pygrub, line 677, in ? fs = fsimage.open(file, get_fs_offset(file)) IOError: [Errno 95] Operation not supported I decided to 100% verify that the filesystem was in fact created as ext3. # losetup /dev/loop0 /var/lib/xen/images/fedora12.img # kpartx -a /dev/loop0 # mount /dev/mapper/loop0p1 /mnt # mount | grep /dev/mapper/loop0p1 /dev/mapper/loop0p1 on /mnt type ext4 (rw) Wait...what? But I specified ext3 in the kickstart file... So how do I get anaconda on Fedora 12 to honor the --fstype=ext3 option for part /boot? I tried both: --fstype ext3 and --fstype=ext3 with the same results.

Is qemu running as well? So, for example F9 had a Xen based kernel and it actually ran fine for me... Alas, I do not have great harware and running F11 using qemu was painful at best - to the tune I just will not do it... I was hopeing 12 might have a Xen based kernel so I can just do like I was with F9... On Tue, 24 Nov 2009, R P Herrold wrote: On Tue, 24 Nov 2009, Scot P.

Re: [CentOS-virt] Shell command to list cpu usage for KVM guests?

I see that capability in virt-manager, but that would require me to install a GUI on the host. Is there a simple report from a command line tool? Something like the three load average numbers per guest in a list? I took a look at virsh but could not find anything. Look at virt-top from epel. Works something like top and shows all guests. # rpm -q virt-top virt-top-1.0.1-7.el5 Steve ___ CentOS-virt mailing list CentOS-virt@centos.org http://lists.centos.org/mailman/listinfo/centos-virt
