Re: Re: [Xen-devel] How can I use grant table in domainU?

Yes, I've tried some of the xen command , but all of them return this error : 
"Unable to connect to xend: No such file or dirctory. Is xend running?"

Then I found the infomation in xend-debug.log, which I've send in last mail.

Here is the content of xend.log:

[2011-04-13 20:35:52 6937] DEBUG (tcp:96) Listening on :8002

 but since I set loglevel to DEBUG in xend-config.sxp, it changed to this:

[2011-04-14 23:40:21 6477] INFO (SrvDaemon:332) Xend Daemon started

When I enter "xend start", the output infomation is like this:

Then it stucked here. I have to use control-c to interrupt.

If I use ps -A, it shows that there are four "xend" process :
 
 6306 pts/0    00:00:00 xend
 6376 ?        00:00:00 kworker/1:2
 6442 ?        00:00:00 dhclient3

 6475 ?        00:00:00 xend <defunct>
 6476 ?        00:00:00 xend
 6477 ?        00:00:00 xend

And some other xen related processes, xenbus, etc.

Look also in the xend.log file, and make sure to turn on the DEBUg
options in your /etc/xen/xend-config.sxp file. And read through the
file please.

Have you tried using 'xl'?
