[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] AW: Re: [Xen-devel] Some test results on Xen 4.0 and 2.6.31 / 2.6.32 pvops kernels
Yet another note: the kernel messages that break 00:02.0 come up when I use
2.6.31 kernel,
that means, if it is passing through the 00:02.1 into the pvops DomU, it will
break 00:02.0.
Please note that this will work with 2.6.18.8
BR,
Carsten.

pvops kernels
Two additional infos: here lspci of the two USB controllers. The 00:02.0 is
passed into another DomU. I
should mention that I think the 00:02.0 is going down in case I pass 00:02.1
into the 2.6.32 domain, but
not if I pass it into the 2.6.31 domain. Find what the other DomU says below.

pvops kernels
Hi,
I am sorry to say that I mixed something. What does work now is
2.6.31.13 kernel. The error
messages are gone now for 2.6.32.11, but it is still not functioning.
So, with the 2.6.32.11 kernel, it will not recognize the same USB
controller that is recognized
by 2.6.31.13.
When booting:

When I detach and attach from Dom0, it will log in the DomU:

In Dom0 we have:

For reference, the log entries when I detach/attach the device in

Did so and move to Xen 3.4.3-rc4 and latest 2.6.18.8 Dom0 kernel. It
works now with pvops 2.6.32.10 DomU kernel!!!
Thanks Pasi!!!
Eventually, you may put on the Wiki Page an example with more than one
PCI device, so that hectic persons like
me see better that a) it's without parenthesis and b) a comma separated
list ;o).
BR,
Carsten.
