Solaris Xen Drop 66
Just summarize how I managed to install and boot an opensolaris domU (latest drop, nv66) under a Linux dom0 (RHEL 5, x64)1. The instructions in the community documentation here doesn't include a kernel or a ramdisk specification, so the Linux dom0's tools didn't care for it. To get around this, I loop mounted the DVD image.
# mount -o loop 66-0624-nd.iso /mnt
# mkdir /etc/xen/kernel
# cp /mnt/boot/platform/i86xpv/kernel/amd64/unix /etc/xen/kernel/osol_xpv_b66.kernel
# cp /mnt/boot/amd64/x86.miniroot /etc/xen/kernel/osol_xpv_b66.miniroot
2. Create the virtual disk for the Solaris domU
Surf to www.rpmfind.net, and search the rpm package with the key words "qemu, el5, x86_64". Download the matched rpm file, qemu-0.9.0-2.el5.rf.x86_64.rpm.
# rpm -ivh qemu-0.9.0-2.el5.rf.x86_64.rpm
# qemu-img create -f raw solaris.raw 10G
Or, directly create the raw file.
# dd if=/dev/zero of=/etc/xen/vdisks/solaris.raw bs=1k seek=8192k count=1
1+0 records in
1+0 records out
1024 bytes (1.0 kB) copied, 4.4e-05 seconds, 23.3 MB/s
The following xen python config file is created and stored at /etc/xen/configs/opensol.cfg.
# cat opensol.cfg
name = "solaris"
memory = "512"
vcpus = "1"
disk = [ 'file:/home/export/images/ISO/66-0624-nd.iso,6:cdrom,r','file:/etc/xen/vdisks/solaris.raw,hda,w' ]
vif = [ '' ]
on_shutdown = 'destroy'
on_reboot = 'restart'
on_crash = 'destroy'
kernel = "/etc/xen/kernel/osol_xpv_b66.kernel"
ramdisk = "/etc/xen/kernel/osol_xpv_b66.miniroot"
rootdisk = "/dev/dsk/c0d0s0"
extra = '/platform/i86xpv/kernel/amd64/unix -B install_media=cdrom'
Note:
1. The statement in Solaris such as
'file:/etc/xen/vdisks/solaris.raw,0,w'
doesn't work on Linux. Replace it with
'file:/etc/xen/vdisks/solaris.raw,hda,w'
2. # xm creat -c opensol.cfg
Using config file "./opensol.cfg".
Error: (22, 'Invalid argument')
This looks like the error Xen gives you when you try to boot a 32-bit domU on 64-bit dom0 (which is supported in 3.1, but not in 3.0.4-1 which our current bits are based off of).
> kernel = "/etc/xen/kernel/osol_xpv_b66.kernel"
> ramdisk = "/etc/xen/kernel/osol_xpv_b66.miniroot"
for a 64-bit domU:
make sure kernel is the one from:
/cdrom/boot/platform/i86xpv/kernel/amd64/unix
and bootadm is the one from:
/cdrom//boot/amd64/x86.miniroot
also, extra should have the 64-bit kernel:
extra = '/platform/i86xpv/kernel/amd64/unix -B install_media=cdrom'
3. By changing the kernel and miniroot to the 64-bit versions under amd64,
the original failure is really gone. :)
But the new issue comes:
The installation process blocks at the point of
"Setting up Java. Please wait ..."
I've waited for about half a hour. It still blocks there.
4. You need at least 768M for the install bits
included with that iso..I expect that to
go down in time.
Once the install is complete, you can lower
the memory back down.
5. Yes, it passes if I increase the virtual memory to 1024.
However, it still comes into another failure on the way of installation.
I used the file-backed virtual disk and made the file with:
# dd if=/dev/zero of=/etc/xen/vdisk/solaris.raw bs=1k seek=8192k count=1
and pass this file-backed v-disk to Solaris domU with:
disk = [ 'file:/home/export/images/ISO/66-0624-nd.iso,6:cdrom,r','file:/etc/xen/vdisks/solaris.raw,hda,w' ]
During installation after typing 'xm create -c opensolaris.cfg', I allocated the entire disk to SOLARIS and made it auto-layouted.
After this, it comes to an error:
The following disk configuration condition(s) have been
detected. Errors must be fixed to ensure a successful
installation. Warnings can be ignored without causing the
installation to fail.
ERROR: The '/' slice extends beyond HBA cylinder 1023
I tried to layout the partition manually, but not helpful.
