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.

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'.

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 .

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.
