2) Read pattern support for quorum need to be extended for the needs of
the COLO primary. It may be simpler or faster to write a simple
replication driver that writes to N children
starts
replaying it's buffer to disk but then dies part way through the replay.
COLO will use migration to do the first checkpoint, so we can use disk migration
to sync the disk first. And then start disk replication.

Jan suggested a fix that could make it less worse, which is to avoid
allocating any memory while walking the guest page tables. However,
it's not clear if this is hard to do and, more importantly, if it's
in this email plus the fact that the guest
memory may be corrupted, and the guest may be in real-mode even
when paging is enabled
Yes, there are some limitations with this option. Jan said that he
always use gdb to deal with vmcore, so he needs such information.
