[Xen-users] Xen 3.0 - RHEL4u3 guest domain freezes at boot "Warning: unable to open an initial console."
I am trying to run RHEL4 update 3 in a Xen unprivileged domain. I am using a
Dell PowerEdge 2850 server with a single Intel Xeon 2.8 GHz cpu - with 128
megs RAM (cat /proc/meminfo | grep MemTotal). I installed Xen 3.0 on RHEL4
u3 on /dev/sda (33 GB /, 2 GB swap) and then installed RHEL4 u3 again on
/dev/sdb (33 GB /, 2 GB swap). I am trying to run the installation on
/dev/sdb as an unprivileged domain. The problem I am facing is that the boot
of the unprivileged domain freezes saying "Warning: unable to open an
initial console.". This happens even when I am not running any other guest
Domains:
I also have disk dumps of a FC5 installation and its swap space which I have
managed to boot into using the following configuration file:
kernel = "/boot/vmlinuz-2.6-xenU"
memory = 256
name = "fedora.fc5"
vcpus = 2
vif = [ '''' ]
#dhcp = "dhcp"
disk = [''file:/root/fedora/fedora.fc5.img,sda1,w'',
''file:/root/fedora/fedora.swap,sda2,w'']
root = "/dev/sda1 ro"
I am using the following configuration file for the RHEL4 u3 installation on
/dev/sdb:
kernel = "/boot/vmlinuz-2.6.16-xenU"
memory = 512
name = "rhel4_u3"
vcpus = 1
vif = [ '''' ]
hostname = "dblxvmrh02"
#dhcp = "dhcp"
disk = [''phy:sdb1,sda1,w'',
''phy:sdb2,sda2,w'']
root = "/dev/sda1 ro"
extra = "3"
Finally, my /boot/grub/grub.conf looks like:
default=0

The FC5 installation was in fact booting. Nevertheless, I mouted /dev/sdb1 on a local directory and created the the three character devices suggested and it worked. Can''t I use some ramdisk to emulate this functionality? I mean ... without creating the devices.
