[Qemu-devel] [Bug 1516446] [NEW] Migration always causes guest freeze in one direction. |

Public bug reported:
Hello,
I have three debian jessie machines standard installations except for
homebuild qemu-2.4.0 package using the source package from testing. I
had the same problem with the standard debian jessie qemu 2.1 too.
I have host A, B and C.
Migrations work between all combinations of these except A -> B. B -> A
works.
I use libvirt but as per your written request I have run qemu directly
and verified the same problem.
Host A:
qemu-system-x86_64 --enable-kvm -name ashole -cpu kvm64 -m 1024 -drive
file=/mnt/synctest/ashole.raw,if=none,id=drive-virtio-disk0,format=raw,cache=none
-vnc 0.0.0.0:600 -k sv -vga std -device
virtio-blk-pci,scsi=off,bus=pci.0,addr=0x9,drive=drive-virtio-disk0,id=virtio-disk0,bootindex=1
Host B:
qemu-system-x86_64 --enable-kvm -name ashole -cpu kvm64 -m 1024 -drive
file=/mnt/synctest/ashole.raw,if=none,id=drive-virtio-disk0,format=raw,cache=none
-vnc 0.0.0.0:600 -k sv -vga std -device
virtio-blk-pci,scsi=off,bus=pci.0,addr=0x9,drive=drive-virtio-disk0,id=virtio-disk0,bootindex=1
-incoming tcp:0:4444
Then in qemu monitor I run migrate -d tcp:B:4444 and the guest freeze.
I have tried with these guest os:es, freebsd 9.1, debian wheezy and
debian jessie (Standard 3.16 kernel and backported 4.2 kernel), same
problem with all of them. when running the migration through libvirt
virt-manager says the guest is using 100% cpu.
I had a similar problem
(https://bugzilla.kernel.org/show_bug.cgi?id=61971) 2 years ago which
was solved in kernel 3.13 if I remember correctly.
Best Regards
Magnus

Title:
Migration always causes guest freeze in one direction.
Status in QEMU:
New
Bug description:
Hello,
I have three debian jessie machines standard installations except for
homebuild qemu-2.4.0 package using the source package from testing. I
had the same problem with the standard debian jessie qemu 2.1 too.
I have host A, B and C.
Migrations work between all combinations of these except A -> B. B ->
A works.
I use libvirt but as per your written request I have run qemu directly
and verified the same problem.
Host A:
qemu-system-x86_64 --enable-kvm -name ashole -cpu kvm64 -m 1024 -drive
file=/mnt/synctest/ashole.raw,if=none,id=drive-virtio-disk0,format=raw,cache=none
-vnc 0.0.0.0:600 -k sv -vga std -device
virtio-blk-pci,scsi=off,bus=pci.0,addr=0x9,drive=drive-virtio-disk0,id=virtio-disk0,bootindex=1
Host B:
qemu-system-x86_64 --enable-kvm -name ashole -cpu kvm64 -m 1024 -drive
file=/mnt/synctest/ashole.raw,if=none,id=drive-virtio-disk0,format=raw,cache=none
-vnc 0.0.0.0:600 -k sv -vga std -device
virtio-blk-pci,scsi=off,bus=pci.0,addr=0x9,drive=drive-virtio-disk0,id=virtio-disk0,bootindex=1
-incoming tcp:0:4444
Then in qemu monitor I run migrate -d tcp:B:4444 and the guest freeze.
I have tried with these guest os:es, freebsd 9.1, debian wheezy and
debian jessie (Standard 3.16 kernel and backported 4.2 kernel), same
problem with all of them. when running the migration through libvirt
virt-manager says the guest is using 100% cpu.
I had a similar problem
(https://bugzilla.kernel.org/show_bug.cgi?id=61971) 2 years ago which
was solved in kernel 3.13 if I remember correctly.
Best Regards
Magnus
