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.

Doc Text:	Attempting to migrate a Windows guest virtual machine that was using the virtio-net-pci device from a Red Hat Enterprise Linux (RHEL) 6 host to a RHEL 7.3 host previously caused the guest to terminate unexpectedly, because the ctrl_guest_offloads feature was disabled on the destination host. This update enables ctrl_guest_offloads on the destination host, and the described migration works as expected.	Story Points:	---

Description Marcel Kolaja 2016-11-08 12:11:24 UTC

This bug has been copied from bug #1378334 and has been proposed
to be backported to 7.3 z-stream (EUS).

Comment 4 Miroslav Rezanina 2016-11-30 10:42:19 UTC

Fix included in qemu-kvm-rhev-2.6.0-28.el7_3.1

Comment 6 huiqingding 2016-12-20 04:01:38 UTC

Reproduce this bug using the following version:
Source RHEL6.8.z host:
kernel-2.6.32-642.13.1.el6.x86_64
qemu-kvm-rhev-0.12.1.2-2.491.el6_8.3.x86_64

Destination RHEL7.3 host:
kernel-3.10.0-514.6.1.el7.x86_64
qemu-kvm-rhev-2.6.0-28.el7.x86_64

Reproduce steps:
1. boot a win10-64 guest in source host:
# /usr/libexec/qemu-kvm \
-enable-kvm \
-m 2G \
-smp 2 \
-M rhel6.6.0 \
-nodefconfig \
-nodefaults \
-cpu SandyBridge \
-rtc base=localtime,driftfix=slew \
-boot order=cd,menu=on \
-device piix3-usb-uhci,id=usb,bus=pci.0,addr=0x1.0x2 \
-drive file=en_windows_10_enterprise_x64_dvd_6851151.iso,if=none,media=cdrom,id=drive-ide0-1-0,readonly=on,format=raw \
-device ide-drive,drive=drive-ide0-1-0,id=ide0-1-0,bus=ide.0,unit=1 \
-chardev pty,id=charserial0 -device isa-serial,chardev=charserial0,id=isa_serial0 \
-device usb-tablet,id=input0 \
-cdrom /usr/share/virtio-win/virtio-win-1.9.0.iso \
-monitor stdio \
-qmp tcp:0:4444,server,nowait \
-vnc 0.0.0.0:0 \
-vga cirrus \
-drive file=win10.raw,if=none,id=drive-ide0-0-0,format=raw,serial=mike_cao,cache=none \
-device virtio-blk-pci,drive=drive-ide0-0-0,id=ide0-0-0 \
-netdev tap,script=/etc/qemu-ifup,downscript=no,id=hostnet0,vhost=on \
-device virtio-net-pci,netdev=hostnet0,id=net0,mac=00:52:4c:23:4d:90

2. install virtio-net-pci driver (virtio-win-1.9.0-3) inside guest

3. boot the guest in destination host with "-incoming tcp:0:5800"

4. do migration
(qemu) migration -d tcp:10.73.196.161:5800

Actual results:
after step4, migration is failed and the destination qemu-kvm quits with
(qemu) qemu-kvm: Features 0x301f99a7 unsupported. Allowed features: 0x719fffe3
qemu-kvm: error while loading state for instance 0x0 of device '0000:00:04.0/virtio-net'
copying E and F segments from pc.bios to pc.ram
copying C and D segments from pc.rom to pc.ram
qemu-kvm: load of migration failed: Operation not permitted

Comment 7 huiqingding 2016-12-20 04:07:35 UTC

Verify this bug using the following version:
Source RHEL6.8.z host:
kernel-2.6.32-642.13.1.el6.x86_64
qemu-kvm-rhev-0.12.1.2-2.491.el6_8.3.x86_64

Destination RHEL7.3 host:
kernel-3.10.0-514.6.1.el7.x86_64
qemu-kvm-rhev-2.6.0-28.el7_3.2.x86_64

Test the same steps as comment #6, the result is that migration can be finished normally.

Comment 8 huiqingding 2016-12-20 04:08:24 UTC

Based on comment #7, set this bug to be verified.
