Hello list,
I was following the instructions for XEN with Gentoo and able to set up
an running domain 0 with x86_64. This was very easy but I must have
done a big mistake because I am still unable to start any guests...
I was trying several configurations (for the guests) but without any result.
/etc/xen/xend-config.sxp
---
(logfile /var/log/xend.log)
(loglevel DEBUG)
(xend-relocation-hosts-allow '^localhost$')
(network-script network-bridge)
(vif-script vif-bridge)
(dom0-min-mem 196)
(dom0-cpus 0)
/etc/xen/test
---
kernel = "/boot/vmlinuz-2.6.16.18-xenU"
name = "test"
memory = 256
disk = [ 'phy:xenDiskGroup/test,sda1,w' ]
root = "/dev/sda1 rw"
The device /dev/xenDiskGroup/test is a partition with reiserfs where I
copied the domain 0 system. I changed the fstab inside this system to
have /dev/sda1 mounted as /. When I start this guest, it stopps after a
few seconds:
xen ~ # xm create /etc/xen/test -c
Using config file "/etc/xen/test".
Started domain test
xen ~ #
The logfile /var/log/xend.log only says "Domain has shutdown" ...
"reason=reboot". After the second restart of this guest, XEN stops this
guest "to avoid loops"...
"[2006年06月07日 13:02:41 xend] INFO (XendDomain:363) Domain test (18) unpaused.
[2006年06月07日 13:02:52 xend.XendDomainInfo] INFO (XendDomainInfo:836)
Domain has shutdown: name=test id=18 reason=reboot"
What do I need to do to see any output of this guest? I was trying to
give any additional information to the kernel to see anything on the
serial device (extra = "com1=9600,8n1 console=ttyS0 debug") but also
without result.
If I mount /dev/xenDiskGroup/test to /mnt/test then I am able to chroot
to this location.
Any suggestions? The kernel config for the domU is the same as for dom0,
despite the following settings:
[ ] Privileged Guest (domain 0)
< > PCI device backend driver
< > Block-device backend driver
< > Network-device backend driver
< > TPM-device backend driver
<*> Block-device frontend driver
<*> Network-device frontend driver
< > Block device tap driver
< > TPM-device frontend driver
[*] Scrub memory before freeing it to Xen
[ ] Disable serial port drivers
< > Export Xen attributes in sysfs
I have no idea what to do next so any suggestions or any ideas are
really helpfull.
Thanks
Arnd
