I am running redhat virtualization.  qemu.  I copied two img files from /var/lib/libvirt/images directory. I also copied server.xml file from /etc/libvirt/qemu. When I tried to import this image on another redhat server, I don't see an option where i can insert this xml file. How do i port the same configuration on other server.


is qemu paravirtulization?

i can't help you much with libvirt but if you run "ps -auxww | grep kvm" or "ps -auxww | grep qemu", you should see the actual command that is run. this command contains something like "... -hda /path/to/disk/image"

if you copy the disk image to another system, and run the same command, changing the path to the disk image to the location where you copied the new one, your vm should fire up

qemu is initially a processor emulator for developpers who want to develop for example arm software on amd64 machines. it evolved into a full-blown virtual machine software in which guests do not need to know they are virtualised in order to run. it is historically slower than other vm software because of the above and the fact it runs in userland. to adress the latter, a kernel module was added by the author a few years afterward. kvm is a linux-specific qemu derivative that is basically qemu running with the kernel module and a couple of optimisations such as directIO that mainly address linux-specific performance and licence problems

noci is right...

Redhat will ignore or chew around your support request because as a loyal customer you are expected to buy RHEV manager...
