Note: This bug is displayed in read-only format because the product is no longer active in Red Hat Bugzilla.
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.

Comment 1 Fabian Deutsch 2021-11-25 10:57:17 UTC 
I'm requesting the testing with Windows 10 and (not yet available on CNV) 11
Comment 3 Li Xiaohui 2022-01-09 13:18:36 UTC 
Test wsl2 on rhel 9.0.0, wsl2 and win10 guest work well.

Test environment:
hosts: kernel-5.14.0-32.el9.x86_64 & qemu-kvm-6.2.0-1.el9.x86_64
cpu of src and dst host: AMD EPYC 7313 16-Core Processor
guest: 
1)win10 guest(q35+seabios), fedora-33 as wsl2;
2)win11 guest(q35+ovmf), ubuntu-20.04 as wsl2.


Test scenarios:
1. ping-pong migration with win10 + wsl2;
2. ping-pong migration with win10(running netperf) + wsl2(running stress);


Test result:
Migration succeeds, Win10/Win11 and wsl2 works well before/after migration, cpu usage is normal in whole migration process.

Comment 4 Li Xiaohui 2022-01-09 13:22:04 UTC 
Updated some parts in Comment 3:
Test wsl2 on rhel 9.0.0, wsl2 and win10/win11 guest work well.

Test environment:
hosts: kernel-5.14.0-32.el9.x86_64 & qemu-kvm-6.2.0-1.el9.x86_64
cpu of src and dst host: AMD EPYC 7313 16-Core Processor
guest: 
1)win10 guest(q35+seabios), fedora-33 as wsl2;
2)win11 guest(q35+ovmf), ubuntu-20.04 as wsl2.


Test scenarios:
1. ping-pong migration with win10/win11 + wsl2;
2. ping-pong migration with win10/win11(running netperf) + wsl2(running stress);
