Re: [Xen-users] Xen 3.1.4: HVM Configuration

["Omer Khalid" <Omer.Khalid@xxxxxxx>]

Hi Todd,

I tried both xvc0 and hvc0 but it didn't work! I kept on getting the same message "xenconsole: Could not read tty from store: No such file or directory".

But when I put <serial='pty'> in the vm config file; then the console seems to start but hangs...And the only way out is Cntrl-]. 

By looking at the xen mail archives, it seems that HVM based VM suffer from this problem. Unfortunately, I don't have the VNC for this machine other wise i could have accessed the console through it.

Additionally, I also tried the following combinations in the vm config file:

<console="/dev/console">, <console="/dev/tty1">, <console="/dev/ttyS0">

I also tried the above combinations with the modifications to /etc/inittab file for getty:

co:2345:respawn:/sbin/agetty <ttyS0><console> 9600

But no luck :((((

Any ideas?

Cheers

Omer

How is your Linux guest setup?

You will need the appropriate console specified on the kernel command line...

hvc or xvc, I forget which is which at the moment, but you should be able to
search the mailing list archives for that (try xen.markmail.org)
(One is for the older xen linux kernels and one is for the mainline xen linux
kernels)

You will also want to make sure that the linux guest has the xen
console support
in it.

Hope that helps,

Todd
