[Xen-users] Xen 3.3 Windows xp guest insufficient resources

[Anzi <anzi@xxxxxxxxxxxxxxx>]

Hello all,

Been using Xen a while, previously with Netbsd and few weeks ago changed 
dom0 to Gentoo linux. Change wen't very nice, but now I'm facing strange 
out of resources problem in Windows XP HVM guests. At first there was no 
issues but when we added second windows guest users started to complain 
that they cannot access network drivers and cannot unzip large zips ( 
the operation stucks at some point). After that we started to notice 
same kind of behaviour in our first (previously fully working windows 
guest). I have used GPL PV drivers 0.9.9 (tried also with 0.9.12.pre4 
and yesterday tried without PV drivers (without /gplpv switch). I have 
tried pretty much everything that comes to my mind without no luck, so 
if anybody have had same kind of sympthons, please, please let me know 
(and hopefully also with answer how you managed to solve this problem).
Windows guests have 700 MB of ram reserved (tried also with 1GB). Both 
are using same base installation of windows from 10 Gb image file (C:\). 
First uses data disk partition from external Sata disk (My Book Studio 
II 2TB), second is using 100 GB file backed image..
Exact windows error info is:

"ERROR: insufficient system resrouces exits to complete the requested 
service".
And Last night the hole machine had crashed (ie not able to do anything 
but turn off from powerswitch, i have now serial console attached..)
