Hi,
I'm running Xen-2.0.4 on a machine with 2 GB of memory.
I compiled a linux-2.6.10-xenU kernel with HIGHMEM=y
to make it able to use more than 896 MB of memory.
I then created a domain with memory=1024 name=Highmem, and then
did an 'xm balloon 256', which caused the xenU-kernel to crash.
# xm list
Name Id Mem(MB) CPU State Time(s) Console
Domain-0 0 123 0 r---- 63.5
Highmem 1 1 1 ----c 5.5 9601
and 'xm destroy Highmem' does not have any effect.
When I created a domain with memory=800 name=Highmem, and then
did an 'xm balloon 256', it worked fine.
Am I doing something wrong? Is this a known problem, or
does it work for everybody else?
