[Xen-devel] [XSM:ACM] When cw is used, dom0 reboots.

[Syunsuke HAYASHI <syunsuke@xxxxxxxxxxxxxx>]

Hi ,

When cw is used, dom0 reboots.
Though I set quest memory size.

I want to study into the cause.
Please teach how to examine it.




#xm create vm1.conf <--  OK
#xm create vm4.conf <--  NO
................... <--  system boot
