Hi xen developers,
You''re the best, Xen Rulez. Although I''ve subscribed to
xen''s mailing list I
post and I never get an answer, I hope this time this mail went somewhere.
I''ve PV''ed CentOS 5.3 i386 as DomU with CentOS 5.4 x86_64 as
Dom0. I have
this OpenVox Telephony card (Openvox A1200P with 1 FXS and 1 FXO modules). I
want to use on the Virtualized OS, I ahd to twak a lot to get it running,
and I had to use the xend-pci-permissive.sxp because the dreaded "driver
tried to write...."
lspci on my Dom0 says:
01:09.0 Communication controller: Tiger Jet Network Inc. Tiger3XX Modem/ISDN

pciback 0000:13:04.0: Driver tried to write to a read-only
configuration space field at offset 0xe0, size 2. This may be
harmless, but if you have problems with your device:
1) see permissive attribute in sysfs
2) report problems to the xen-devel mailing list along with details of
your device obtained from lspci.
PCI: Enabling device 0000:13:04.0 (0000 -> 0003)
Although Now I see the device on DomU, whenever I try to load the DAHDI
2.2.0 drivers I get this on dmesg on Dom0, and it hangs to death after some
time.
Do you have a strange power saving mode enabled?
Uhhuh. NMI received for unknown reason 00.
Dazed and confused, but trying to continue
Do you have a strange power saving mode enabled?
Anyway, The only way to solve this issue was to use xend-pci-permissive.sxp
adding:
(unconstrained_dev_ids
(''e159:0001'') # OpenVox A1200P
)
Hope this helps you
Thanks again.

I haveI was under the impression that 5.4 (2.6.18-128.el5) did not have the pciback module. Either way, I would recommend you use the pv-ops [1] and try that one. If you still have trouble with the pv-ops, please include more details: dmesg of both DomU and Dom0, lspci -vvv of both domains, and boot your Xen with guest_loglvl=all ... snip ..> Anyway, The only way to solve this issue was to use xend-pci-permissive.sxp > adding:..snip..> (unconstrained_dev_ids > (''e159:0001'') # OpenVox A1200P > )I am reading this as, it fixed the warning about the device not being safe, but did not help with your Dom0 hang?
