It's specifically the second volume group that collides between virtual and physical systems. Both dom0 and U have identical VolGroup00 VGs, but these do not collide. Renaming the VG used by the domU within the domU removes the collision, but the newly-renamed VG still shows up in dom0 as a useable VG with space to be allocated. Here is the pvdisplay output from dom0. Interestingly, it shows /dev/VolGroup01/lv-sys1-data as "physical volume" when it's obviously just an LV in the original VolGroup01 VG. And this only happens with the _second_ Volume Group created. VolGroup00 is not an issue on this or any other systems I've used: [root at iain2 qemu]# pvdisplay --- Physical volume --- PV Name /dev/VolGroup01/lv-sys1-data VG Name vg-sys1 PV Size 40.00 GB / not usable 4.00 MB Allocatable yes (but full) PE Size (KByte) 4096 Total PE 10239 Free PE 0 Allocated PE 10239 PV UUID FTA4QU-ydZ7-e2Yy-nBsi-t4st-3jj7-IAkQH8 --- Physical volume --- PV Name /dev/sda3 VG Name VolGroup00 PV Size 39.06 GB / not usable 29.77 MB Allocatable yes (but full) PE Size (KByte) 32768 Total PE 1249 Free PE 0 Allocated PE 1249 PV UUID tTViks-3lBM-HGzV-mnN9-zRsT-fFT0-ZsJRse --- Physical volume --- PV Name /dev/sda2 VG Name VolGroup01 PV Size 240.31 GB / not usable 25.75 MB Allocatable yes PE Size (KByte) 32768 Total PE 7689 Free PE 5129 Allocated PE 2560 PV UUID ZE5Io3-WYIO-EfOQ-h03q-zGdF-Frpa-tm63fX [root at iain2 qemu]# cat sys1.xml <domain type='kvm'> <name>sys1</name> <uuid>37f34394-d380-d2c4-ac37-3263c16028ff</uuid> <memory>524288</memory> <currentMemory>524288</currentMemory> <vcpu>1</vcpu> <os> <type arch='x86_64' machine='rhel5.4.0'>hvm</type> <boot dev='hd'/> </os> <features> <acpi/> <apic/> <pae/> </features> <clock offset='utc'/> <on_poweroff>destroy</on_poweroff> <on_reboot>restart</on_reboot> <on_crash>restart</on_crash> <devices> <emulator>/usr/libexec/qemu-kvm</emulator> <disk type='block' device='disk'> <driver name='qemu' cache='none'/> <source dev='/dev/VolGroup01/lv-sys1'/> <target dev='vda' bus='virtio'/> </disk> <disk type='block' device='cdrom'> <target dev='hdc' bus='ide'/> <readonly/> </disk> <disk type='block' device='disk'> <source dev='/dev/VolGroup01/lv-sys1-data'/> <target dev='vdb' bus='virtio'/> </disk> <interface type='network'> <mac address='54:52:00:3b:4a:f5'/> <source network='default'/> <model type='virtio'/> </interface> <serial type='pty'> <source path='/dev/pts/3'/> <target port='0'/> </serial> <console type='pty' tty='/dev/pts/3'> <source path='/dev/pts/3'/> <target port='0'/> </console> <input type='mouse' bus='ps2'/> <graphics type='vnc' port='-1' autoport='yes' keymap='en-us'/> </devices> </domain> -- -- - Iain Morris iain.t.morris at gmail.com -------------- next part -------------- An HTML attachment was scrubbed...
