Hi @hellohellenmao , would you please help to review this patch? Thanks.

Hi @fbq815 , @xiagao, could you please help review it? Many thanks.

@zhencliu we use memory-backend-file on s390x when we use memory-backend with virtio-fs, please reference to the usage of avocado-framework/avocado-vt@85915c0

[fbq815]

Test log on s390x:
RHEL.10:
s390x.io-github-autotest-qemu.virtio_fs_nfs_migration_handler.s390-virtio: PASS (54.05 s)

RHEL.9:
virtio_fs_nfs_migration_handler.s390-virtio: PASS (57.22 s)

@zhencliu the case LGTM and I'll ack once you update the note in the py file

How about calling it cmd_wait_file as 'Get-Content' use -wait parameter instead of -tail.

[zhencliu]

Thanks for the reply. Actually 'Get-Content -wait' does mostly like what 'tail -f' does on Linux, so I use cmd_tail_file, to keep consistent for both Linux and Windows

Thanks Xiaoling, it seems it's easy to hit errors when testing on win2025, I will do some tests later, thanks for the verification

[hellohellenmao]

Passed with rhel10 guest, and the log looks good to me. Thanks.

Hi @xiagao The root cause is tasklist cannot list the whole powershell command in Win2025, I updated the code, it can now work fine.
Hi @fbq815 , memory-backend-file issue updated in both commit and cfg.

Test passed on Win2025/Win2022/RHEL9.6

[xiagao]

Great, thanks @zhencliu. I might review those patches two or more weeks later as I'm busy on our projects recently.
