[libvirt] Create a new VM from an existent image?
Hi, To use libvirt, I am strying to use virt-install to create a new VM from an existent (KVM) VM image. I did the following steps: 1) run libvirtd with "libvirtd -d" (I use the latest libvirt git tree) 2) Run virt-install (0.400.3) with my existent image in img/img.winxp # virt-install --import -n winxp -f img/img.xp3 --vnc --hvm --accelerate --ram 800 However, this step returns error like: "ERROR Could not find usable default libvirt connection." Actually I am not sure that is the right way to use the new --import option with virt-install. So that might be the problem? All the code are updated, and compiled from source on Ubuntu 8.04. Any help? Thanks a lot, J

That looks fine.
However, this step returns error like:
"ERROR Could not find usable default libvirt connection."
If 'virsh --connect qemu:///system' doesn't work, you probably didn't configure your libvirt install correctly. - Cole

But it works! So the problem stays elsewhere. Do you have any suggestion? Thanks, J

Hmm, then you probably need this patch to virtinst, since our URI detection likely isn't as thorough as libvirt: http://hg.et.redhat.com/cgi-bin/hg-virt.cgi/applications/virtinst--devel/rev... - Cole

I got the latest code from hg tree, and installed that. But running "virt-install" (without option) returns the error message: Traceback (most recent call last): File "/usr/local/bin/virt-install", line 36, in <module> from virtinst.VirtualCharDevice import VirtualCharDevice ImportError: No module named VirtualCharDevice How to fix this problem? Thanks, J
