[Xen-users] xen not working: xmlrpc.sock doesn't exist

[supermanue <supermanue@xxxxxxxxx>]

Hi all,

I have some serious problems making Xen run. I have spent a couple of days
looking in Google and trying a lot of different things, but none of them has
worked.  I hope you can help me...  
First of all: xen was running smoothly on my machine, but suddenly (I think
I haven't changed any configuration) it doesn't work anymore. 

I am using  a Debian 4.0 with Xen 3. 

When I run /etc/init.d/xend start, it works ok.  With ps -aux | grep xen I
get the following output:
root        12  0.0  0.0      0     0 ?        S<   20:06   0:00 [xenwatch]
root        13  0.0  0.0      0     0 ?        S<   20:06   0:00 [xenbus]
root      4148  0.0  0.1   1732   676 ?        S    20:07   0:00 xenstored
--pid-file=/var/run/xenstore.pid
root      4156  0.0  0.1  10152   480 ?        S    20:07   0:00 xenconsoled
root      4157  0.0  0.1  10152   480 ?        S    20:07   0:00 xenconsoled
root      4158  0.0  0.1  10152   480 ?        S    20:07   0:00 xenconsoled
root      4691  0.0  0.8   9340  3808 ?        S    20:34   0:00 python
/usr/sbin/xend start
root      4692  0.5  1.0  17504  4648 ?        Sl   20:34   0:00 python
/usr/sbin/xend start

It looks OK. 


But when i try xm list the following error arises
Error: Error connecting to xend: No such file or directory.  Is xend
running?

This is a very common error. Many people solves it by creating /var/run/xend
and /var/run/xenstored by hand. I did it, and gave them +777, so the problem
is not here.


/var/log/xend.log has the following content:

[2007-06-27 20:34:58 xend] INFO (__init__:1072) Xend Daemon started

    domlist = xc.domain_getinfo()
error: (38, 'Function not implemented')


also, I tried strace xm list 2>&1 to see what's exactly happening. 
Everything works correctly until it tries to open /var/run/xend/xmlrpc.sock
, wich doesn't exists. this is the output. 

socket(PF_FILE, SOCK_STREAM, 0)         = 3
connect(3, {sa_family=AF_FILE, path="/var/run/xend/xmlrpc.sock"}, 27) = -1
ENOENT (No such file or directory)
geteuid32()                             = 0
write(2, "Error:", 6Error:)                   = 6
write(2, " ", 1 )                        = 1
write(2, "Error connecting to xend: No suc"..., 70Error connecting to xend:
No such file or directory.  Is xend running?) = 70
write(2, "\n", 1)                       = 1


I don't know if I have posted too much information, but I don't really have
any clue of what's going wrong, so can't decide what is important and what
isn't. 


Excuse me for my poor english.

Thanks for your help, 

Manuel
