My host kernel is 2.6.26.2. And My host has 8GB memory and 4GB swap. Guest can be live migrated, but after that, guest will call trace. Maybe we can have a check with each other's environment. My steps as following: 1. qemu-system-x86_64 -incoming tcp:localhost:4444 -m 4096 -net nic,macaddr=00:16:3e:44:1a:a6,model=rtl8139 -net tap,script=/etc/kvm/qemu-ifup -hda /share/xvs/var/rhel5u1.img 2. qemu-system-x86_64 -m 4096 -net nic,macaddr=00:16:3e:44:1a:a6,model=rtl8139 -net tap,script=/etc/kvm/qemu-ifup -hda /share/xvs/var/rhel5u1.img 3. In qemu console, type "migrate tcp:localhost:4444" The call trace messages in guest: ################### Kernel BUG at block/elevator.c:560 invalid opcode: 0000 [1] SMP last sysfs file:

Comment By: Avi Kivity (avik) Date: 2008-11-23 15:18 Message: Fixed by new migration protocol from upstream qemu. ---------------------------------------------------------------------- Comment By: Anthony Liguori (aliguori) Date: 2008-05-26 12:48 Message: Logged In: YES user_id=120449 Originator: NO The issue isn't actually the use of phys_ram_base. In the case of migration, we don't care about the layout of physical memory. We just want to look at memory from phys_ram_base .. ram_size. The problem is that we encode physical addresses in the migration protocol as 32-bit values. We'll need to figure out a way to switch to encoding PFNs while maintaining backwards compatibility with the current code. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=893831&aid=1971512&group_id=180599 -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
