[libvirt-users] Excluding RAW disk from snapshot
by Trey Dockendorf 02 Aug '12

02 Aug '12

I have an oVirt engine node that currently runs the system on a qcow2 based virtual disk, and an NFS export volume on RAW. I'd like to take a snapshot before a somewhat risky upgrade of oVirt and can't with the raw image attached. Looking at the documentation for the snapshot XML, I created this XML file for the snapshot <domainsnapshot> <name>20120802</name> <description>oVirt 3.1 upgrade</description> <disks> <disk name='vda' snapshot='yes' /> <disk name='vdb' snapshot='no' /> </disks> </domainsnapshot> When I try the snapshot I get this error... # virsh snapshot-create dc-vmarchitect dc-vmarchitect_ss.xml error: argument unsupported: unable to handle disk requests in snapshot This occurred on both libvirt-0.9.4 and after an upgrade to libvirt-0.9.10 Current system is CentOS 6.2 with 6.3 versions of qemu/libvirt qemu-kvm-0.12.1.2-2.295.el6_3.1.x86_64 qemu-img-0.12.1.2-2.295.el6_3.1.x86_64 libvirt-client-0.9.10-21.el6_3.3.x86_64 libvirt-python-0.9.10-21.el6_3.3.x86_64 libvirt-0.9.10-21.el6_3.3.x86_64 According to the documentation, http://libvirt.org/formatsnapshot.html, the disk features should be available since 0.9.5. Is this still missing or have I created an invalid XML? Thanks - Trey

[libvirt-users] Using virsh to load scripts for the guest machine
by Mauricio Tavares 02 Aug '12

Right on the top of http://www.centos.org/docs/5/html/5.2/Virtualization/chap-Virtualization-Ma…, it seems to imply you can load/send scripts to the vm guest using virsh. Is that possible? How and what are the limitations? Can you query the vm guest?

[libvirt-users] libvirt: how to set PV-on-HVM drivers??
by zcs 01 Aug '12

01 Aug '12

Hi friend. I have a problem about using libvirt now. There is a feather about HVM driver ---PV_on_HVM_drivers, in xm configure, using flag xen_platform_pci can control the feather, but in libvirt I can not find the flags to use pv-on-HVM drivers. So I want to find the answer if the libvirt can control the modules using xml file? thanks a lot. best regards. zhong.chunshan http://wiki.xen.org/wiki/Xen_Linux_PV_on_HVM_drivers
