Error report from attempt to run an HVM instance

[Michael Litchard]

Tried to run an HVM instance, here's the error report I got.

Could it be because you're trying to connect to a serial console,
while you have none configured ?

Re: Error report from attempt to run an HVM instance

[Michael Litchard]

I'm not intending to, I used the hvm script that came with pkgsrc. I
can't find any
line in the script that suggests trying to connect to a serial
console. If there is a line, could you point it out to me?

You're using 'xm create -c'
-c instructs to connect to console

Replace these two disk lines by this:

disk = [ 'phy:/dev/wd0i,ioemu:hdb,w', 
'file:/sys/domains/domU3/amd64cd.iso,ioemu:hdc:cdrom,r' ]

Re: Error report from attempt to run an HVM instance

[Michael Litchard]

okay the instance is created

# /usr/pkg/sbin/xm list
Name                                        ID   Mem VCPUs      State   Time(s)
Domain-0                                     0  1024     1     r-----     57.3
hvm-netbsd                                   1   256     1     r-----    237.2

but when I did a xm create -c I got this error, and again when I tried
to attach to the console
# /usr/pkg/sbin/xm console hvm-netbsd
xenconsole: Could not read tty from store: No such file or directory

I'm close. The config file is the same except the changes christoph suggested.
What can I do now?

This is not the way you connect to a HVM console, unless you configured
the HVM guest to use a serial console. By default it's the HVM's virtual
framebuffer.

The virtual framebuffer can be displayed in 2 ways, depending on the config
file:
1) using the SDL library. qemu-dm will  open a X window on the $DISPLAY
   from which xm create was run. If $DISPLAY isn't valid, I think the
   guest will start without console display.
2) qemu-dm act as a vnc server. You connect to the console using vncviewer
   on localhost. As you only have one guest, I guess it''ll be
   vncviewer localhost:0
