Hi,
I'd like to know if there is a configuration file for each KVM virtual
machine? I can define a domain by "virsh define" command, but where
the configuraiton parameters are persisted for the VM?
Thanks in advance!
Regards,
Qian

virsh is not a part of kvm, but rather libvirt; you should ask for
support for it on the libvirt mailing list.
That said -- you can list defined VMs through "virsh list --all", edit
them through "virsh edit", and dump their XML via "virsh dumpxml". The
config files are kept in /etc/libvirt/qemu, but you SHOULD NOT edit them
directly -- just like /etc/sudoers should be edited only through visudo,
/etc/libvirt/qemu/* should be edited only through libvirt methods (which
can be accessed through the virsh command); this makes sure libvirtd is
always aware of any changes, and prevents invalid configuration from
ever being written to disk.
