Version: 4.0.1-2
Severity: normal

When creating Xen DomU's, at some point xend invokes the oom-killer and
the entire machine restarts:

xm info says the machine has 10231 MB of RAM. These are the VMs that
normally run:
Name ID Mem VCPUs State Time(s)
Domain-0 0 2177 1 r----- 127.1
one 1 1536 2 r----- 192.4
two 2 512 1 -b---- 2.7
three 3 1024 1 -b---- 188.6
four 4 512 1 -b---- 12.7
five 5 2048 2 -b---- 151.7
six 6 1024 2 r----- 64.9
seven 7 1024 2 -b---- 65.9
eight 8 1024 2 -b---- 100.7
That means 8704 MB of memory is used.
Over the last couple of days, I've experienced that when creating two
VM's with 512 MB RAM, the oom-killer is invoked. This should not happen
because Dom0 can shrink and because the machine should not restart when
it is out of memory.
This is a production Xen host, which is becomming a liability, because
it's so unpredictable.
