1045334 – Migration failed for different qemu-kvm version on two hosts

RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description langfang 2013-12-20 07:48:24 UTC

Description of problem:
Migration failed for different qemu-kvm version .

Version-Release number of selected component (if applicable):
Host A:
# uname -r
3.10.0-63.el7.x86_64
# rpm -q qemu-kvm
qemu-kvm-1.5.3-30.el7.x86_64

Host B:
# uname -r
3.10.0-61.el7.x86_64
# rpm -q qemu-kvm
qemu-kvm-rhev-1.5.3-21.el7.x86_64


Guest:win2008sp2-32

How reproducible:

100%

Steps to Reproduce:
1.Boot guest on Host A
 /usr/libexec/qemu-kvm -enable-kvm -M pc-i440fx-rhel7.0.0 -cpu Opteron_G1,hv_spinlocks=0x1fff,hv_relaxed,hv_vapic -m 2048 -smp 2,sockets=2,coresads=1 -name usb-device -uuid c43826c6-8d42-4574-80c5-e78e0dd6b232 -rtc base=localtime,clock=host,driftfix=slew  -drive file=/mnt/win2008sp2-32-newinstall.qcow2_v3,if=none,id=drive-system-disk,format=qcow2,aio=native,werror=stop,rerror=stop -device virtio-blk-pci,scsi=off,drive=drive-system-disk,id=system-disk,bootindex=2,addr=0x3 -netdev tap,id=hostnet0,script=/etc/qemu-ifup,downscript=no -device virtio-net-pci,netdev=hostnet0,mac=00:15:65:01:3a:20,addr=0x4 -global PIIX4_PM.disable_s3=0 -global PIIX4_PM.disable_s4=0 -spice port=5830,disable-ticketing -vga qxl -monitor stdio -qmp tcp:0:4444,server,nowait -serial unix:/tmp/tty0,server,nowait -device virtio-balloon-pci,id=balloon0,addr=0x9 -boot menu=on

2.Host B
...-incoming tcp:0:5999

3.Migrate from HostA--->HostB
(qemu)migrate -d tcp:10.66.106.21:5999

Actual results:
Src-->HostA:
(qemu) migrate -d tcp:10.66.106.21:5999
(qemu) info migrate
capabilities: xbzrle: off x-rdma-pin-all: off auto-converge: off zero-blocks: off 
Migration status: failed
total time: 0 milliseconds
(qemu) info status
VM status: running

Des:-->Host B
(qemu) Unknown ramblock "/rom@genroms/kvmvapic.bin", cannot accept migration
qemu: warning: error while loading state for instance 0x0 of device 'ram'
load of migration failed


Expected results:

Can be migrate successfully

Additional info:

1)If migrate from hostB--->host A,successfully


2)Host B:
model name	: AMD Phenom(tm) II X4 B95 Processor


Host A:
model name	: AMD Opteron(tm) Processor 4284

Comment 1 langfang 2013-12-20 07:50:30 UTC

addtional info: If update two hosts qemu-kvm version to the same version (EG:qemu-kvm-1.5.3-30.el7.x86_64),migration successfully.

Comment 3 Orit Wasserman 2013-12-20 11:21:13 UTC

Hi,
Can you print the output of /proc/cpuinfo on both hosts?

Comment 5 Orit Wasserman 2013-12-23 08:05:37 UTC

Does it happen when you migrate from the same qem version on this hosts?
(qemu-kvm or qemu-rhev)
