[libvirt-users] XML file format for snapshot-create
I've created a very basic snapshot XML file, to allow for a description of the snapshot. However when running the virsh command, it doesn't like the formatting. # virsh snapshot-create proxy_0 /vmstore/proxy_0/proxy_0_ss.xml error: XML description for failed to parse snapshot xml document is not well formed or invalid This are the XML file contents... # cat proxy_0_ss.xml <domainsnapshot> <name></name> <description>Before updating to CR repo</desciption> </domainsnapshot> I'm running libvirt-0.8.7 on CentOS 6 x86_64. I can take snapshots just fine without defining the XML file, but I'd like to be able to add a description. Thanks - Trey

That's because:
This are the XML file contents...
# cat proxy_0_ss.xml <domainsnapshot> <name></name>
If <name> is present, it must not be empty.
<description>Before updating to CR repo</desciption> </domainsnapshot>
If you want libvirt to generate the name for you, then omit <name>; otherwise, provide a non-empty name alongside your description.

Newer libvirt also has: virsh snapshot-create-as --description 'Before updating to CR repo' proxy_0 which creates the XML for you, and thus is a bit easier to use. Alas, that would mean you'd have to upgrade. -- Eric Blake eblake@redhat.com +1-801-349-2682 Libvirt virtualization library http://libvirt.org

Thanks for the response. Unfortunately I still receive the exact same error with only this as the contents... <domainsnapshot> <description>Before updating to CR repo</desciption> </domainsnapshot> I also tried filling in a name, and still the same error. Thanks - Trey

-> it seems to be something rather silly: your closing tag misses an 'r': it should be </description>
Grts, Jürgen
Yep that is silly. Thanks for catching that! I'd been staring at it so long, and even went to the source to see what could trip it up. Thanks again, it works! - Trey
