For me everything is solved with installation of Linux 6.5.11-7-pve kernel.
Working without problems with mitigations=off
Live migrated 400GB server image /over 10Gbit network/ and lot of smaller ones, LInux and Windows,
Cluster has uptime about 14 days after complete upgrade, about 50 VMs...

to GRUB_CMDLINE_LINUX_DEFAULT="mitigations=off"
Servers in internal network, performance more important than worying about Spectre and Meltdown vulnerability
some problem here on older Intel(R) Xeon(R) CPU E5-2697 v2 @ 2.70GHz
as bonus, filesystems corrupted, probably because i was migration guests wtih 128GB RAM

This one was imported from backup made on stopped VM
virtio0: local-lvm:vm-116-disk-0,cache=none,media=disk,size=80G
And...
And does qcow2 over LVM-thin make sense ? Here is stated, that only raw format is suported on LVM-Thin storage
