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.
Yeah , I was referring to 0.9.4-rc2 :) I will install the official libvirt 0.9.4 tomorrow .
I tried installing in my Centos 5.6 machine. After a successful installation, when I start virsh , I get :
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).
I think so, I installed libvirt 0.9.4-rc2 on Centos 6 and it worked fine. I tried installing in Centos 5.6 (It had libvirt already installed through yum) . I did yum remove libvirt. Then I did ./configure --prefix = / , make , make install , ldconfig. When I enter virsh after finishing these steps, I get that error. I am not sure whether I am committing a mistake in-between. Please correct me if I am wrong. Thank you.
