[Xen-devel] I cannot get any message from domU by console.

[박은병 <peb1611@xxxxxxxxx>]

I had installed xen 3.4.2 & pvops 2.6.31.6 dom0 kernel

 

and, I was trying to boot domU kernel as same as dom0

 

distribution is ubuntu 9.10(karmic)-server, i386

 

I confirmed kernel configuration several time.

 

$> xm create ubuntu1.config -c

Using config file "./ubuntu1.config".
Started domain ubuntu1 (id=4)

<----------------------------------------->

   ( this is space)

 

that was all. no other message was appeared.

 

$> xm list

Name                                        ID   Mem VCPUs      State   Time(s)

$>ifconfig -a

eth0

..............

vif4.0

...............

 

$> xm block-list 4

2049   0    0     1      -1     -1    /local/domain/0/backend/vbd/4/2049 
2050   0    0     1      -1     -1    /local/domain/0/backend/vbd/4/2050

 

$> xm console 4

 

==> I think that domU booting is good, but I cannot get the any console message

 

<configuration file-ubuntu1.config>

kernel = "/boot/vmlinuz-2.6.31.6-xenU"

ramdisk = "/boot/initrd.img-2.6.31.6-xenU"

memory = 512

name = "ubuntu1"

vif = [ 'bridge=xenbr0' ]
ip = "192.168.0.101"
netmask= "255.255.255.0"
gateway = "192.168.0.1"

disk = [ 'file:/root/xen/domainU/ubuntu1/ubuntu1.img,sda1,w','file:/root/xen/domainU/ubuntu1/ubuntu1_swap.img,sda2,w' ]

root = "/dev/sda1 ro" 

extra = "console=hvc0"

 

I also tried to hvc0 console by googling

 

</etc/init/hvc0.conf>

start on stopped rc RUNLEVEL=[2345]
stop on runlevel [!2345]

respawn
exec /sbin/getty -8 38400 hvc0

 

what is problem?? first, I am wondering whether domU's booting is good or bad

and if good, why not console message??
