Xen users - Jun 2008 - unable to access Linux HVM via xm console - Could not read tty from store: No such file or directory

Hi all

I''m running CentOS 5.1 x64 + Xen 3.0 & I have setup a CentOS 5.1
x64
domU as a HMV. For the setup I used VNC, but I would prefer to be able 
to access it via "xm console cPanel" via SSH directly.

Here''s the output cPanel HVM:

[root@pc-00059 ~]# more /etc/xen/cPanel
name = "cPanel"
uuid = "ff940501-507d-04ca-e590-831e79ba0397"
maxmem = 6144
memory = 6144
vcpus = 2
builder = "hvm"
kernel = "/usr/lib/xen/boot/hvmloader"
boot = "c"
pae = 1
acpi = 0
apic = 0
on_poweroff = "destroy"
on_reboot = "restart"
on_crash = "restart"
device_model = "/usr/lib64/xen/bin/qemu-dm"
sdl = 0
vnc = 0
vncunused = 2
#disk = [ 
"phy:/dev/data/cPanel,hda,w","file:/data/storage/CentOS-5.1-x86_64-bin-1of7.iso,ioemu:hdc:cdrom,r"
]
disk = [ "phy:/dev/data/cPanel,hda,w" ]
vif = [ "mac=00:16:3e:4e:9b:48,bridge=xenbr0,type=ioemu" ]
serial = "pty"
usb = 1
usbdevice = ''tablet''


When I try and connect to it via console, I get the following:
[root@pc-00059 ~]# xm console cPanel
xenconsole: Could not read tty from store: No such file or directory
[root@pc-00059 ~]#



Reading through all the email archives, I found a few similar problems, 
but the suggested fixes doesn''t help. Does anyone know how to get xm 
console to work for HVM type domU''s ?

mmm, now that I think of it. I setup fully virtualized hosts, not HVM - 
my bad.....
