RE: XEN 4.0 + 2.6.31.13 pvops kernel : system crashes on starting 155th domU

I did make that change (dom0_mem=8192M), but I still get the same error.
When I started the 154th domU (last time it was 155th) the dom0 crashes
(it kills network connections and I have to manually go and reboot it). I
did get a little bit more information on xend.log and daemon.log
(attached).  After the last successful VM startup I did check and make
sure the dom0 did indeed have enough memory.

root@MESL-BlackBox:/home/xen/noswap-configs# xm list | grep testing | wc
-l
153
root@MESL-BlackBox:/home/xen/noswap-configs# xm info | grep mem

total_memory           : 24490

Using config file "./testing-ss-157.ucsd.edu".

/var/log/daemon.log  --> daemon.log <attached>
/var/log/xend.log    --> xend.log   <attached>

We'd appreciate any pointers to fix this...

Thank you

You might want to use dom0_mem=<X>M option for xen.gz instead.
