Is this what is happening?: http://lists.xensource.com/archives/html/xen-devel/2008-12/msg01030.html i.e. the guest does not have a balloon driver causing the PoD cache to run out of pages and so crashing the domain? also: 09 - xend integration. + Always calls xc_hvm_build_target_mem() with memsize=maxmem and target=memory. If these the same, the internal function will not use PoD. Trying this now. Success!! The 32hv12 machine is alive and kicking!!! Just set MAXMEM=MEMORY and PoD is disabled!! Very happy here. Now for WinXP. Cheers V On Fri, 4 Jun 2010 10:53:40 am Virgil wrote: > Further notes on WinXP crashes: > > What we did was attempt to install XP many many times.
