I'm running xen 3.03 with ubuntu (kernel 2.6.16.29-xen) with a number
of Win2K, WinXP, Linux guests. The hardware platform is Intel(R)
Xeon(R) CPU 5160. I'm having the following problem :
Sometimes one WinXP machine seems to die/reboot and that brings the
whole system in
a state where any commands like xm list|shutdown|create seems to hang.
Doing an strace of "xm list" gives me :

futex(0x62a530, FUTEX_WAKE, 1)          = 0
futex(0x62a530, FUTEX_WAKE, 1)          = 0
futex(0x62a530, FUTEX_WAKE, 1)          = 0
futex(0x62a530, FUTEX_WAKE, 1)          = 0
socket(PF_FILE, SOCK_STREAM, 0)         = 3
connect(3, {sa_family=AF_FILE, path="/var/run/xend/xmlrpc.sock"}, 27) = 0
sendto(3, "POST /RPC2 HTTP/1.0\r\nHost: \r\nUse"..., 132, 0, NULL, 0) = 132
sendto(3, "<?xml version=\'1.0\'?>\n<methodCal"..., 151, 0, NULL, 0) = 151
recvfrom(3,

And that's it... it hangs. Norw the fact that a WinXP guest dies is
the least of my problem.
What I'm really after is how can I interart again with xen, so I cluds
create/switch off other machines ?
