[Xen-devel] xenoprofile cannot run in active mode in domU

[K L <intervalmg@xxxxxxxxx>]

Dear all,

I have enable xen-3.4.2 oprofile configuration and compiled the
oprofile-0.9.5.tar.gz with patch oprofile-0.9.5-xen.patch.

I 'scp' the xen-syms kernel and the vmlinux kernel to domU. I want to
start the mode with:

opcontrol --start --event=CPU_CLK_UNHALTED:1000000:1:1:1 --xen
xen-syms-3.4.2 --vmlinux=vmlinux

But it shows the result like:

testvm02:~# opcontrol --start --event=CPU_CLK_UNHALTED:1000000:1:1:1
--xen xen-syms-3.4.2 --vmlinux=vmlinux You cannot specify any
performance counter events
because OProfile is in timer mode.

I have read previous thread 'Xenoprof: getting Oprofile out of timer
mode?'(http://copilotco.com/mail-archives/xen.2006/msg12482.html). It
seems the problem has been fixed. But why I cannot run xenoprofile in
active mode in domU. Does it have something to do with apic?(I have
configured in /etc/xen/testvm02.cfg with lapic)

My machine is HP proliant. I can provide further information if needed.

Thanks,
Jeff
