'Blocked' is the normal state (unless you mean 'Paused'). Domains are
only 'Running' when they are using CPU.
Doesn't a guest domain (or any OS) always use CPU, at least 0,01% or
something similiar?
For example i'm running a Windows SBS 2003 as Domain Controller with
Sharepoint Services and Exchange Server and virsh list tells me the
domain is blocked.
Can you ping the domains (if they have a network connection)? Or view
their console?
I can access the domains with vnc.
Since i undefined and redefined all domains i can't ping the guest from
the host and when i am connected with vnc i can't ping anything. The
windows guest does have a nic and has an ip in the same network as the
the host.
It should be a bridge setup.
<interface type='bridge'>
<source bridge='virbr0'/>
<target dev='vif6.0'/>
<mac address='00:16:3e:33:eb:7b'/>
<script path='vif-bridge'/>
</interface>
ifconfig tells me there is a peth0, tap, virbr0 and vif6.0 interface.
I'm running F7 on a Dell PE2950 with 8GB RAM.
It would be nice if you could explain how much RAM i should allocate
to Dom0 and what are the minimum requirements for Dom0.
I would expect that allocating 512 MB to Dom0 as you did should be
sufficient (unless it's running a huge database or something like that).
The problem, though, isn't likely to be the allocation, but the fact
that you are using 'virsh setmaxmem' to balloon it down from something
larger to 512 MB. In any case, I'm not sure what the problem is -
unless you can find something in a logfile, it's hard to tell.
After i allocated 512MB RAM to Dom0 the kernel printed many out of
memory messages like this and began to kill services.
