[Xen-devel] Require solution for "xenoprof: Initialization failed. Intel processor model 44 for P6 class family is not supported“
HI all :
I got the message "Using timer interrupt." when trying the
command
"opcontrol --list-events". then I found infomation "xenoprof:
Initialization
failed. Intel processor model 44 for P6 class family is not supported“ after
"xm dmesg". the TYPE OF CPUS here is Intel(R) Xeon(R) CPU E5620 @
2.40GHz.
So does it really not support this type of processor and is there
any fix that may solve it ？ need help...
.
Thanks~

This CPUs work fine for me with 4.1.1. 2011/6/28 fred <dujian1985@gmail.com>:> HI all : > I got the message "Using timer interrupt." when trying the command > "opcontrol --list-events". then I found infomation "xenoprof: Initialization > failed.

Hi Konrad:
the version of Xen hypervisor is 3.4.3 and the version of kernel is
2.6.18. I don''t know why it works well in physical machine and fails
in virtual machine ?

I don''t know why it works well in physical machine and fails > in virtual machine ?Because virtual machines aren''t allowed to have direct access to host performance counters; the VM has to ask Xen to do it. Performance counters are very specific to individual processor models; so Xen needs support for specific processor models for the guest to be able to use performance counters rather than simply using a timer interrupt. Those changes are typically not backported to older releases (although there''s no reason maintainers couldn''t do so if they chose.) -George> > 2011/6/28 Konrad Rzeszutek Wilk <konrad.wilk@oracle.com> >> >> On Tue, Jun 28, 2011 at 03:24:04PM +0800, fred wrote: >> > HI all : >> > I got the message "Using timer interrupt." when trying the >> > command >> >> You need to provide more details.
