New subject: [libvirt] [PATCH 1/2] virDomainMigrateUnmanagedParams: Don't blindly dereference @dconnuri
This function may be called with @dconnuri == NULL, e.g. from
virDomainMigrateToURI3() if the flags are missing
VIR_MIGRATE_PEER2PEER flag. Moreover, all later functions called
from here do wrap it into NULLSTR() so why not do the same here?

New subject: [libvirt] [PATCH 2/2] virt-host-validate-common: Print warning on missing IOMMU
No only coverity warns about this, but it kind of makes sense
too. We have a test whether host supports IOMMU. Some platforms
don't have it, I know. But in that case we should print a message
that it's unknown whether platform has it or not.
Before:
(no output)
After:
QEMU: Checking for device assignment IOMMU support : WARN
(Unknown if this platform has IOMMU support)
