What do the guests use for storage? (e.g. "blktap2 for VHD files on an iscsi
mounted ext3 volume")
It might be worth looking at /proc/kernel/slabinfo to see if there's anything
suspicious.
BTW: 24 vCPUs in dom0 seems a excessive, especially if you're using stubdoms.
You may get better performance by dropping that to e.g. 2 or 3.
