Hi, there is a question.
I need to observe some Xen internals, so i thought debugging might be useful. i
tried using gdb, kdb, ... but they are complicated and not obvious. there is a
debugging
tool, GNU DDD, which may be suitable (although some simple) for that. but
unfortunately i can not fi
Hi,
I need to know what happens while a cpu which is running a vcpu, suddenly crash
or down? I mean have xen any plane for such a situation?
in other word what will happen for a vcpu which it's related cpu get down
suddenly (i mean for vcpu which has that crashed cpu's affinity)?
Thanks and reg

I hope getting your meaning correctly.
hi, I need to know how we can migrate a vcpu context while running from one
core to another core? is it possible via scheduler?
would you please guide me through this goal?
thanks and regards.

Does xenpm 'cpufreq' or 'cpuidle' feature, has any effect on scheduling
decisions?

Hi,
I know that scheduling is done via two main functions and their effective
interaction:
one 'schedule()' in schedule.c and another 'do_schedule(...)', which is
specific for every scheduling policy.
my question is that (although it may seem clear and very common for kernel
developers, but not

Hi all.
I've recently changed and added some line of code in some functions of credit
scheduler, then issue:
make clean
make world
(fix compilation errors, if any)
make install
rm -f /boot/xen.gz
and update-grub
then reboot the system to change to dom0, but when grub is loaded and i choose
"ubunt

installing xen?

Hi,
I added a new hypercall to xen successfully, but when i try to invoke it in

i created for it.

This is the second (and last) time I'm saying this:
if Xen works (either inside of VMware, or everywhere else) up until you
modify it, and then it stops working after you've modified it, there's
99.99% probability that it is your modifications that are wrong.
Yes, I know it and i mentioned it
