Description Guowen Shan 2022-01-24 07:20:06 UTC

This bug is created to enable virtio-mem from QEMU side on ARM64. The
corresponding guest kernel work is tracked by bug 2044155. The similar
work has been done on x86 via bug 2014484

Comment 1 Guowen Shan 2022-01-28 07:10:35 UTC

The QEMU patches have been merged to upstream.

b1b87327a9 hw/arm/virt: Support for virtio-mem-pci
1263615efe virtio-mem: Correct default THP size for ARM64

Comment 2 Guowen Shan 2022-04-06 01:09:36 UTC

This depends on the work to enable virtio-mem in kernel, which is tracked
by bug 2044155

Comment 6 Guowen Shan 2022-04-25 07:08:55 UTC

Zhenyu, virtio-mem device is available now from the following package.
I also tried the 'qemu-kvm' binary and virtio-mem works as expected.

Thanks,

Comment 7 Miroslav Rezanina 2022-04-25 12:10:40 UTC

Removed Fixed in version as this BZ require additional changes.

Comment 10 Zhenyu Zhang 2022-05-06 07:45:09 UTC

Testing, will update the results later.

Comment 15 Zhenyu Zhang 2022-05-07 08:45:38 UTC

Hello Gavin,

According to comment11-14 I think virtio-mem verification is complete, 
Since this patch has been merged into downstream so I want to set the bug as closed currentrelease.
What do you think?

Comment 17 Zhenyu Zhang 2022-05-07 09:19:37 UTC

Close this bug as current-release according to comment15 and comment16.

Comment 18 Zhenyu Zhang 2022-05-09 06:10:06 UTC

Hello Miroslav,

Sorry to bother you.
Although this bug has actually been verified, but according to Workflow QE needs to wait for the bug to become ON_QA before setting verify.
So I reverted the bug to the previous MODIFIED state and set Verified: tested
Please help to change the bug status.
