Description Jeremy Katz 2006-02-07 13:43:03 EST
VMX guests don't cause dom0 to auto-balloon as paravirt guests do.  Probably
just needs some logic brought over to the vmx builder
Comment 1 Jeremy Katz 2006-02-07 15:31:20 EST
Hrmm, it's all common code. 
tools/python/xen/xend/XendDomainInfo.py:initDomain() is where the balloon call
occurs and then it's followed almost directly by the memory_increase_reservation.  
Comment 2 Jeremy Katz 2006-02-07 17:56:42 EST
Urk, this is caused by the device model requesting more memory to store the
video RAM in.  Bad hack committed to CVS so that we account for that when
ballooning at domain creation, but it needs a better solution for
upstream/long-term.  Filed upstream as
Comment 5 Jeremy Katz 2006-09-05 13:48:51 EDT
A nice fix for this went upstream earlier today
