Hi
In an exercise to use more libvirt, I am trying to use libvirt with my
normal use. First, I will explain how I normally run my guests.
I install guests on a machine with virt-install <....>
I store all my guests images in a shared directory that is mounted in
all my hosts.
Now, it is trivial for me to launch qemu-kvm <options> on any machine,
it don't matters if I have to use a rhel5, rhel6, fedora13 host.
Everything works as expected.
Except for the little fact that I have to remember the whole command
line when I go from one machine to other, to use ide/virtio/rtl8139/....
You get the idea. And thing got worse the more guests that I have.
Now I can run virt-manager on my desktop (machine A).
Connect to host B. And launch my guests VM1 (on host B). No problem so far.
I can indeed migrate my guests to machine C. No problem so far.
And now I can start my guest VM1 in both host B and host C. It is there
on virt-manager, one click away of launching.
The functionality that I would really like is a "way" to store my guest
information on my desktop (machine A), and be able to launch the guest
on any host. I.e. a menu option when I click on the guest, that let me
launch it in a different host, not in the one that it is defined.
If that is difficult to implement for now, a "migrate" for a shut off
guest will do by now. It should be something like
virsh dumpxml foo > foo.xml
virsh define foo.xml
(this is the way that I do it by hand now).
Why do I need this? because I have hosts with RHEL5/RHEL6/F13/....
And just now, I have to reinstall, do the previous dumpxml/define each
time that I have to reproduce one bug in one host or another. To make
things worse, sometimes RHEL5.4 and RHEL6.0 xml's are not completely
compatible and I have to fix it by hand.
Any better ideas about how to do this?
Notice that I think that RHEV-M does something like this, but debugging
on a RHEV-M host is an exercise on pain (everything is read only, ...)
Later, Juan.
