Libvirt shoots for monthly releases; the current schedule is feature freeze this weekend, then a release around the first of August.

The new API will allow you do to either:

virsh dumpxml --inactive --dom>  file.xml
edit file.xml
virsh save dom dom.save --xml file.xml
virsh restore file.save

or:

virsh dumpxml --inactive --dom>  file.xml

Using --inactive here only works if you haven't made any changes to the inactive configuration that differs from the currently running domain. I'd amend this step to 'virsh dumpxml dom > file.xml' for both of these examples.

virsh save dom dom.save
edit file.xml
virsh restore file.save --xml file.xml

These two examples will be supported in 0.9.4.  Additionally, I added:

virsh save-file-dumpxml dom.save > file.xml
virsh save-file-define dom.save file.xml
virsh save-file-edit dom.save

to do things inline, and to make it so you don't have to remember to 'virsh dumpxml dom' prior to 'virsh save'.


I found that the latest libvirt (libvirt 0.9.4) is out.

That's amazing, considering it hasn't been released yet :) Maybe you are referring to 0.9.4-rc2 instead? But at any rate, the official 0.9.4 will probably be released tomorrow with even more bug fixes above 0.9.4-rc2.

virsh: /lib/libvirt.so.0: version `LIBVIRT_PRIVATE_0.8.2' not found (required by virsh)

Is it possible to get the latest version of libvirt 0.9.4 work on Centos 5.6 ?  Thanks a lot for your help.

Yes, it should be possible, although I haven't tried it myself on centos (but I have tried on RHEL 5.7). Are you sure you installed your self-built libvirt.so correctly? We take great pains to ensure that libvirt.so is backwards compatible (no symbols are ever removed).
