> Subject: [PATCH v7 3/7] vhost: fix missing cache logging NUMA realloc
> 
> When the guest allocates virtqueues on a different NUMA node
> than the one the Vhost metadata are allocated, both the Vhost
> device struct and the virtqueues struct are reallocated.
> 
> However, reallocating the log cache on the new NUMA node was
> not done. This patch fixes this by reallocating it if it has
> been allocated already, which means a live-migration is
> on-going.

> Fixes: 1818a63147fb ("vhost: move dirty logging cache out of virtqueue")
