This is to request installation help for a Xen 3.1 guest domain. Xen installation source was CentOS 5.1 DVD. Dom0 and a guest(clientdom) have been installed, but clientdom cannot be connected to. Issuing command "xm create -c clientdom" generates message lines: Using config file "./clientdom". Started domain clientdom xenconsole: Could not read tty from store: No such file or directory"xen top" shows clientdom (as well as Domain-0) started, but "xm console clientdom" produces the same error, "xenconsole: Could not read tty fromstore: No such file or directory."HVM guests as far as I know don't yet support consoles. You should use either sdl=1 or vnc=1. If you use vnc you should make sure that xen-config.sxp has the vnc options enabled and configured to your liking. You may also need to manually start the vncviewer to see the guest console. The default setting when enabled let's you do vncviewer localhost.Also, don't pass the -c on the command line, since you can't get an initial (text) console with the HVM guest.This is not true. If you are running a Linux/Unix guest as HVM, you can get the initial boot messages and text console if you pass -c to the "xm create", but only after you configured your kernel to pass boot messages to serial console. Start up of a linux hvm guest on my system looks as below.[root@dhcp6-7 ~]# xm create rhel4_hvm -c Using config file "/etc/xen/rhel4_hvm".
