Title:
KVM: after upgrading the kernel to 5.15.0-75, VM hangs after
migration.
Status in linux package in Ubuntu:
Confirmed
Bug description:
I have weird situation when I am live migrating a VM between two
nodes, the VM hangs after migrating from EPYC3(Milan) to EPYC1(Naples)
nodes.
First node:
CPU(s) AMD EPYC 7713 64-Core Processor (2 Sockets)
Linux compute81 5.15.0-75-generic #82~20.04.1-Ubuntu SMP Wed Jun 7 19:37:37
UTC 2023 x86_64 x86_64 x86_64 GNU/Linux
Second node:
CPU(s) AMD EPYC 7401 24-Core Processor (2 Sockets)
Linux compute37 5.15.0-75-generic #82~20.04.1-Ubuntu SMP Wed Jun 7 19:37:37
UTC 2023 x86_64 x86_64 x86_64 GNU/Linux
When I am migrating from second type node to first type - everything works.
When I am migrating from first type to second type - VM freezes
No issues using the following kernels:
5.15.99 from upstream
linux-image-5.15.0-25-generic_5.15.0-25.25_amd64
