 Hi,all
   xen: 4.1.2
   dom0 linux: centos 3.1.10 #1 SMP Tue Jun 26 17:13:57 EDT 2012 x86_64
x86_64 x86_64 GNU/Linux

   I enabled ACM and install xen-4.1.2 correctly, dom0 can also boot
successfully, but if i use command xm create to create a domU, dom0 reboots.

   Does xen-4.1.2 support ACM, or how can i solve this bug?

   please help me.

   many thanks !

I don't know about 4.1 but ACM has been removed from 4.2 so it will
become unsupported in the future. In reality it had been unmaintained
for some time before that so I wouldn't be surprised if it was broken in
4.1 as well.

Given that I don't know how worthwhile it is to spend time
diagnosing/fixing ACM in 4.1, but in any case you would need to supply
console logs and the like before any progress could be made. Please see 
http://wiki.xen.org/wiki/Reporting_Bugs_against_Xen for guidance on the
sort of information which a good bug report should contain.

Perhaps you should consider transitioning to FLASK which remains
supported?

Ian.

Please don't top post. It makes it hard to flow the flow of a
conversation.

I'm afraid I don't know.

Given that it has been already been removed from unstable due to being
unmaintained for quite a long time I would recommend you not deploy new
systems using it even if you find an old version which happens to work.
