Dear: I think that I installed the libvirt by rpms automatically , then it does have a fixed location of the file--libvirt.xml , I want to know where is the file(the fixed location). Thanks! 2012/3/8 Evaggelos Balaskas <ebalaskas@ebalaskas.gr>

There are a lot of ways to find one file in linux/unix systems. You can use find, locate or via rpm with rpm -ql libvirtd

Hi all: My OS is now Fedora16 , and the spice server is installed on it by rpms. Then I run 'qemu-kvm -hda /root/vaddsoft.img -m 512 -vga qxl -spice port=5930,disable-ticketing' , I want to find out where is the

libvirt.xml

for the command . Well , I mean that the libvirt.xml is genrated automatically, not by myself manually. Wish your help! Thanks a lot!

If you start a guest with qemu command line directly, there is no libvirt XML for it, libvirt doesn't try to manage guest which is not created through libvirt API.

However, you _can_ teach libvirt about certain guests started directly by qemu; the 'virsh qemu-attach' command can attach to guests that were properly started with a socket monitor.

For a guest created through libvirt, and it's persistent, the persistent XML is stored in /etc/libvirt/qemu/, and the running state XML is in /var/run/libvirt/qemu/, and

Note that these files are to be treated as read-only. If you want to modify the guest, you must not edit these files, but instead should use commands like 'virsh edit' for the persistent definition, and hotplug actions like 'virsh add-device' for the live definition.

you would see the generated qemu command line by libvirt either by

# ps -ef | grep qemu

# cat /var/log/libvirt/qemu/$guest.log
