I'm on a crash course with Xen .... got some quick questions.
Hardware is Dual 3GHz EM64T CPUs on an IBM x346 machine.
Using Squeeze amd64 installation with lvm2, all good so far. Using 6
disks with the ServeRAID-7k presenting 6 logical -- I've RAID6-ed 3
partitions, the first for /boot, the second for swap and the third for lvm2.
Don't have HVM, so using para-virtualization.
I found that I couldn't start the Dom0 machine too quickly, so I changed
the grub timeout from 5 seconds to 10 seconds -- if I start it too
quickly, then it bombs out [panic] and does a reboot. After waiting the
full 10 seconds, all is fine. Is there a setting that would help with
this so that the Dom0 can be started immediately?
Other grub adjustments were made, Xen kernel first and no OS probing.
Using xen-tools to create DomU machines (one squeeze using debbootstrap
only so far).
Adjusted these two entries in /etc/default/xendomains
# By default, when Xen dom0 shuts down or reboots, it tries to save the
# state of the domUs. Sometimes there are problems with that and
# because it is also clean to just have the VMs shutdown upon host
When you reboot the Dom0 machine without first shutting down the DomUs,
does it do a normal shutdown of each DomU cleanly? It looks like it
does a very fast halt, so I'm not sure the shutdown would be as clean as
I would like.
My first DomU machine is 1 hour slower than my Dom0 machine, how should
I properly synchronize the times?
