Re: Question on stopping KVM start at boot
Hi Dustin, - snip - Where shall I add "-b" option? Thanks modprobe -b says "respect the blacklists". See: * http://manpages.ubuntu.com/manpages/lucid/en/man8/modprobe.8.html -b --use-blacklist This option causes modprobe to apply the blacklist commands in the configuration files (if any) to module names as well.

Hi Alex, Thanks for your advice. Just qemu-img convert the image to raw and use that as disk image in vbox. Make sure you configure your vm to the same hw as on kvm (apic, piix3, etc) Could you please explain in more detail "... configure your vm to the same hw as on kvm (apic, piix3, etc)"? The image file of vm is *.qcow2. I'll run VirtualBox on KVM if possible. The former is desktop virtualization. Ah a further thought can convert vm across PCs? That is VirtualBox is running on another PC. But seriously, why would anyone want to go this direction? I can't get sound work on vm. Therefore I expect trying VirturlBox to check whether it can sort out this problem. I'll run VirtualBox on KVM if possible. The former is desktop virtualization. B.R.

Convert KVM to VirtualBox
Hi folks, I need converting KVM (qcow2) to VirtualBox (vdi) from one PC to another PC. Google didn't find many threads concerned, instead the other way around. However it found only one; How to Convert a KVM to a VDI http://www.ehow.com/how_5856610_convert-kvm-vdi.html If I read the article correctly it seems both KVM and VirtualBox are running on the same PC, VirtualBox running on KVM. Do you have any idea/suggestion where can I find relevant documentation? TIA. B.R.

Re: Can VM be copied to another PC (Solved)
Hi kashyap, Thanks for your advice. Quoting Kashyap Chamarthy : On Mon, Feb 1, 2010 at 9:32 AM, wrote: - snip - 1) 'virsh dumpxml '(this will dump the guest machine info. into XML) 2) copy your qcow2(or whatever format) image files from host1 to host2(which of similar config as host1) 3) 'virsh define ' for the dumped xml files from step 1) (for each of the guests) 4) Now you should be good to start/run the guests on your host2 running KVM Your milage may vary. See virsh manpages for more. Your advice works here. host-1 Debian 5.0 32bit host-2 Fedora 12 64bit But have to edit /etc/libvirt/qemu/VM.xml changing; /usr/bin/kvm as; /usr/bin/qemu-kvm I tried my steps suggested on my original posting. It works as well. Changing VM.xml as mentioned above is also necessary. B.R.

Can VM be copied to another PC
