Hi, I''ve notice strange thing, all my domUs are listed as blocked: Name ID Mem(MiB) VCPUs State Time(s) Domain-0 0 251 2 r----- 4166.2 g01 28 256 2 -b---- 508.3 g02 26 128 1 -b---- 235.7 g03 35 512 1 -b---- 17.2 although they are running fine. I''m just wondering what can be wrong, because I need proper reporting for some monitoring tools. Host system is Ubuntu Dapper Server running Xen 3.0.1 binary, guests Debians, Ubuntus. Any ideas?

The moment you run the xm command, the CPU is obviously with Domain-0, producing your output. That means, all other domains don`t have the CPU right now, hence are listed as blocked. The only chance to see a domU in a state other than "b" is to use a SMP system. :) /Ernst _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

But as I mentioned above, it''s SMP system, but I''m not using any pin techniques , so all domains are with default vcpu settings. -- Tom Napierala DB Alliance Limited North Point House, New Mallow Road, Cork, Ireland The National Software Centre, Mahon, Cork, Ireland _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

This can be caused because the domain is waiting on IO (a traditional wait state) or has gone to sleep because there was nothing else for it to do. ...

I have a smp and it shows blocked for me too Ernst!
Being SMP doesn''t guarantee that the guests are running when doing xm
info. However, being uni-processor GUARANTEES that Dom0 is the one
running...
"b" means that the guest is blocked, which is the state it is in when
it''s waiting for I/O, timers or other domain(s) to let it run again.
It''s impossible to say which one of those three (or more) possible
causes are actually holding the process up. If you don''t actively do
something in a domain, it will be blocked. The best way to see SMP
systems run is to put some infinite loop in a command shell, or better
yet run an infinite loop in a compiled language, such as
forever.c:
int main(void)
{
for(;;) ; /* doesn''t end */
return 0; /* this is just here to make the compiler happy */
}
gcc forever.c -o forever
./forever
That will make the domain use 100% of it''s allocated CPU time (and any
"spare" cpu-time too, if there is any).
Don''t do this in Dom0, unless you want all DomU''s to run very
slow (and
unless you have Credit scheduler, in which case it MAY work OK).

Hi all!, I am trying the Xen Enterprise solution for our development environment. We use RHEL AS 4.2 and ES 4.0 both 64bits. I can''t find a way of installing them with this version of Xen Enterprise. The repository installation will failed under a different boot image error. If I have VT Server, will be possible to install any OS (Suse,RH,Windows) using the media dvd/cds/network install?
