For your information, we just discovered a regression in Vhost library
introduced in v21.11.2.
The commit listed as being fixed was itself backported to 21.11.1, which
is the one currently documented as supported with OVS master and branch-3.0.
Is it as likely to occur with 21.11.1, or there is some other in-direct
changes in 21.11.2 that make it trigger ?
A deadlock happens when vIOMMU is enabled and NUMA reallocation of
the virtqueues happen. A fix [0] was already posted by David in July and
will soon land into DPDK main branch, so it will likely be in v21.11.3
release.
It sounds nasty enough - assuming there is enough in 21.11.1 to trigger
this, perhaps we should downgrade the documented/supported version for
master/branch-3.0 to 21.11.0 until there is a fix in 21.11.3.
