Sorry. None of the VM images are actually mounted in dom0. Each .img file contains a LVM setup as configured by the OS installer. Here's what the disk looks like (physical; then VM). root@vps [/etc/xen]# df Filesystem 1K-blocks Used Available Use% Mounted on /dev/sda3 611025584 203800484 376186720 36% / /dev/sda1 256666 20642 222772 9% /boot tmpfs 1877400 0 1877400 0% /dev/shm /usr/tmpDSK 495844 10545 459699 3% /tmp none 1877312 160 1877152 1% /var/lib/xenstored root@vps [/etc/xen]# xm list Name ID Mem(MiB) VCPUs State Time(s) Domain-0 0 300 4 r----- 29074.3 server1 22 1249 1 -b---- 15.2 root@vps [/etc/xen]# xm console server1 [root@server1-backup proc]# df Filesystem 1K-blocks Used Available Use% Mounted on /dev/mapper/VolGroup00-LogVol00 150263916 22599896 119907836 16% / /dev/xvda1 101086 27498 68369 29% /boot tmpfs 640088 0 640088 0% /dev/shm Justin Tianen Classic Services (414) 771-0827 jtianen@xxxxxxxxxx > -----Original Message----- > From: Robert Dunkley [mailto:Robert@xxxxxxxxx] > Sent: Tuesday, June 02, 2009 10:03 AM > To: Justin Tianen > Subject: RE: [Xen-users] disk image corruption > > I might be confused here but why are you specifying a filename for the > disk if the VM has its own LVM partition? > > My dedicated LVM partition configs look a bit like this: > disk = [ 'phy:/dev/lvvolumegroup/lvvolume,hda,w'] > > > > -----Original Message----- > From: Justin Tianen [mailto:jtianen@xxxxxxxxxx] > Sent: 02 June 2009 15:58 > To: Robert Dunkley; xen-users@xxxxxxxxxxxxxxxxxxx > Subject: RE: [Xen-users] disk image corruption > > Yes.
