Hello all! It should be fixed https://github.com/vatesfr/xen-orchestra/commit/72592a54d2225d5368a3410e4b3c19039f8e5df1 0 b-Nollet committed to vatesfr/xen-orchestra fix(backups): correctly update allowed_operations - temporary fix (#7924) Fixes https://xcp-ng.org/forum/post/81327 `allowed_operations` are currently not updated correctly when `blocked_operations` are modified, which causes backup jobs to remove `migrate_send` and `pool_migrate` from VM's `allowed_operations`. This commit fixes that, until `allowed_operations` updates correctly again.

Ah good news then

@dinhngtu said in Epyc VM to VM networking slow: @Forza There's a new script here that will help you check the VM's status wrt. the Fix 1. Thank you. It does indeed look like the EPYC fix is active in XOA. [07:25 22] xoa:~$ python3 epyc-fix-check.py 'xen-platform-pci' PCI IO mem address is 0xFB000000 Grant table cacheability fix is ACTIVE.
