[Kernel-packages] [Bug 2024500] Re: KVM: after upgrading the kernel to 5.15.0-75, VM hangs after migration.
Thanks @mloza1 - I see well this looks different from the issue I am investigating, but maybe I can still help. There are 10s of thousands of changes between linux-image-5.15.0-25 and linux-image-5.15.0-67 so it's difficult to know what caused this. I think bisecting the changes is our best bet. Maybe you can try to narrow down which Ubuntu kernel started to fail this use-case? If you can find out which kernel version exactly started to fail that would be helpful. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-hwe-5.15 in Ubuntu. https://bugs.launchpad.net/bugs/2024500 Title: KVM: after upgrading the kernel to 5.15.0-75, VM hangs after migration.
