Large page allocation times out - causes guest hang

[markh]

I'm frequently getting virtualbox guests hanging - unable to use via the UI and unable to ssh in. The virtualbox manager window is also unresponsive after this happens. Host: windows 8.1, 16GB ram Guest: (only 1 running) Ubuntu 15.04,

At the point of the hang, the logs for the VM indicate many lines of

00:25:33.681073 OHCI#0: Lagging too far behind, not trying to catch up anymore. Expect glitches with USB devices

Followed by:

00:26:51.436653 PGMR3PhysAllocateLargePage: allocating large pages takes too long (last attempt 106 ms; nr of timeouts 11); DISABLE

kat_ams, HostMemoryLow. Either decrease the amount of memory assigned to the guest or add more RAM to the host.
