[Xen-users] mythbackend dvb cards...need some guidance...

["Tom Bishop" <bishoptf@xxxxxxxxx>]

Trying to get a myth backend running in fedora core 6 and xend 3.0.3 but having some issues with the DVB ATSC card, I have removed it from Dom0 and presented it to my vm, but I am unable to scan for channels...this is what lspci looks like for the card:

lspci -v
00:00.0 Network controller: Techsan Electronics Co Ltd B2C2 FlexCopII DVB chip / Technisat SkyStar2 DVB card (rev 02)
        Subsystem: Techsan Electronics Co Ltd B2C2 FlexCopII DVB chip / Technisat SkyStar2 DVB card
        Flags: slow devsel, IRQ 18
        Memory at f7ff0000 (32-bit, non-prefetchable) [size=64K]
        I/O ports at ec00 [size=32]


Here is a part of the error message when scanning:

scandvb /usr/share/dvb-apps/atsc/us-ATSC-center-frequencies-8VSB
scanning /usr/share/dvb-apps/atsc/us-ATSC-center-frequencies-8VSB
using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0'
main:2247: FATAL: failed to open '/dev/dvb/adapter0/frontend0': 2 No such file or directory

Here's is wher I removed the modules from dom0:
/sbin/rmmod b2c2_flexcop_pci
/sbin/rmmod b2c2_flexcop

Then I unbind...add new slot and then bind...
echo -n 0000:01:01.0 > /sys/bus/pci/drivers/b2c2_flexcop_pci/unbind
echo -n 0000:01:
01.0 > /sys/bus/pci/drivers/pciback/new_slot
echo -n 0000:01:01.0 > /sys/bus/pci/drivers/pciback/bind

Here's my xen config:

name = "rr-myth"
memory = "256"
disk = [ 'tap:aio:/var/images/rr-myth.img,xvda,w', ]
vif = [ 'mac=00:16:3e:4c:61:eb, bridge=trust', ]
uuid = "b56db1a1-38b8-8751-6e18-684b31f4b36c"
bootloader="/usr/bin/pygrub"
vcpus=1
pci=['01:01.0']
on_reboot   = 'restart'
on_crash    = 'restart'

Have been reading through but not sure if I've missed anything, everything looks good except this last piece, any help would be  much appreciated.  Thanks.
