Description Andrey Ponomarenko 2022-08-11 07:59:53 UTC 
I can't install guest OS in virt-manager due to OOM of virt-manager after upgrade of kernel from 5.18.13 to 5.18.16 on Fedora 35. Reverting back to kernel 5.18.13 fixed the issue.

Tried on this guest: https://download.acronis.com/vstorage/releases/5.0/x86_64/iso/acronis-cyber-infrastructure.iso

Have not tried yet on other guests.
Comment 1 Artem S. Tashkinov 2022-08-11 09:14:48 UTC 
No hardware specs, no guest specs, no errors, nothing.

What should kernel developers deduce from this bug report?
Comment 2 Andrey Ponomarenko 2022-08-11 09:46:53 UTC 
Host hardware specs: https://linux-hardware.org/?probe=69ebaebf95
Guest specs: 4 CPU, 13G RAM, 2 NIC
Error: guest OOM
Comment 3 Andrey Ponomarenko 2022-08-11 09:48:27 UTC 
Not reproduced after reinstalling kernel update to 5.18.16.

Probably this is Fedora update problem or Linux kernel update problem.
Comment 4 Andrey Ponomarenko 2022-08-11 14:11:07 UTC 
Reproduced again on 5.18.16.
