[Xen-ia64-devel] serial console settings on Tiger4

2007-02-08 Thread KUWAMURA Shin'ya
Hi all, At xen-ia64-unstable:13867, the serial console connected to my Tiger4 machine outputs no messages. Do anyone have any ideas? Cset:13773 is good. My setting: append=dom0_mem=2G com2=115200,8n1 console=com2,vga tbuf_size=8 \ dom0_max_vcpus=2 -- console=tty0

Hi, David Okay got some more information this is kinda odd... If you look it does see the two cpu's but later theres a line about Dom0 max_vcpus=1. How did this get set? is this default? could I set this on the commandline to 2? Hmmm, this seems where it's being set... so all I'd have to

Yes. If you alloc two vcpus to dom0, you must add dom0_max_vcpus=2 to command line of xen. If you don't add dom0_max_vcpus, xen alloc one vcpu to dom0. This is default as you said the above. e.g. my elilo.conf image=vmlinuz-2.6.18-xen vmm=xen.gz label=xen

All of the CPUs exposed to dom0 and domUs are virtual CPUs. Xen schedules virtual CPUs across the physical CPUs just like a bare metal OS schedules processes across physical CPUs. The xm top output shows vCPU processor usage across all the vCPUs in a domain. The CPU% shown is the percentage

You can tune the Xen credit scheduler to effectively do what you're asking (I think). AFAIK, dom0 already has some scheduling priority. See here for details on tweaking the credit scheduler: http://wiki.xensource.com/xenwiki/CreditScheduler Thanks, I'll take a look at this, for sure...
