* Bug Report: Live Migration - could someone help me @ 2008-07-04 1:27 ` Chen_PeterK 0 siblings, 0 replies; 4+ messages in thread From: Chen_PeterK @ 2008-07-04 1:27 UTC (permalink / raw) To: kvm-ia64 Hi I am trying the live migration function, but meet some problem: The guest OS was blocked (or maybe dead) on target machine. The symptom is I can not interact with the migrated OS after operation. I believe it's dead, because the mouse can't response and I can't not ping it. Environment: 1. The image was created in format raw or qcow2 (both have been tried) 2. Migrated with TCP or SSH (both have been tried) 3. Host OS: Fedora 9 (2.6.25) 64bit OS 4. Host hardware: support Intel - VT (64bit CPU) 5. Guest OS: Ubuntu 8.04 32bit, Windows XP, Windows 2003 (all have been tried) 6. Shared story is NFS attached. The strange is I can do successful live migration using my friend's image (WinXP raw format) and Tiny Linux (which don't need to install). I think may be I do something wrong. Could someone help me? Many thanks!!! Peter Chen ^ permalink raw reply [flat|nested] 4+ messages in thread

I start my image with command: Source: qemu-kvm -hda /mnt/windows.img -M pc -m 1024 -net nic -net tap,ifname=tap1,script=no -localtime Dest: qemu-kvm -hda /mnt/windows.img -M pc -m 1024 -net nic -net tap,ifname=tap1,script=no -localtime -incoming tcp://0:4444 PS: I also tried other commands, like: qemu-kvm -hda /mnt/windows.img -M pc -m 1024 (no network) Then, migrate from source to destination: migrate tcp://"IP of dest":4444 PS: if I type migrate -d tcp://"IP of dest":4444, and then "info migration". I can see migration do happened. First, it show actived, after finishing transfering all pages, it shows inactived. At last, the image at source become stop, and we can see the right screen shows in destination. The strange is the vm in destination can not response. It’s dead VM. >Is there any significant difference between your XP guest and your friend's >guest (mainly different emulated devices) ? We use the same install image. I do all process in the same way. Best regards!
