I had tried that (and hda1) before, but sda1 I get an error, too:
[root@dyn95394184 xen]# xm create -c test1 vmid=1
Using config file "test1".
Error: Error creating domain: vbd: Device not found: sda1
try disk = [ 'phy:hdc1,0801,w' ]
0801 == sda1
No difference. Same Kernel panic
Something odd is going on here -- I believe other people have had
RHEL3 working.
I believe it. But RHEL 4 has some differences from RHEL 3, among them
the fact that in RHEL 4 the devices in /dev are created dynamically.
Thus, if I mount hdc1 and look at /dev, it is empty. However, /dev in
hdc3 (xen0) has 671 entries. I have a SuSE 9.0 system where the drive
that I export (equivalent to hdc1, in this case) has many devicen on
/dev, meaning they are static; RHEL 3 is similar.
Can you mount hdc1 in dom 0 OK?
Yes:
[root@dyn95394184 ~]# mount /dev/hdc1 /data1
[root@dyn95394184 ~]# df
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/hdc3 6372520 2732376 3316436 46% /
none 251384 0 251384 0% /dev/shm
/dev/hdc1 7055144 2422572 4274180 37% /data1
[root@dyn95394184 ~]#
Is there an sbin/init
[root@dyn95394184 ~]# ls /data1/sbin/init
/data1/sbin/init
[root@dyn95394184 ~]#
? Is there
a dev directory?
Yes, but it is empty:
[root@dyn95394184 dev]# pwd
/data1/dev
[root@dyn95394184 dev]# ls
[root@dyn95394184 dev]#
It might be worth enabling the debugging printks in
drivers/xen/blkfront/block.h and drivers/xen/blockback/common.h
and rebuilding xen0 / xenU.
I created an image file to experiment, and it seems to go a little
further. The problem has got to be related to the /dev issue.
disk = [ 'file:/boot/initrd.x86.image,0801,w' ]
# Set if you want dhcp to allocate the IP address.
# dhcp="dhcp"
# Set root device.
root = "/dev/sda1 ro"
