Hi Simon,
I have tried it. The default virtual slot number (0x20) is shown.
Should not virtual slot numbers be shown in the case?
# cat /etc/xen/vm1 | grep pci
pci = [ '01:00.0','01:00.1' ]
# xm new vm1
Using config file "/etc/xen/vm1".
# xm pci-list vm1
VSlt domain bus slot func
0x20 0x0 0x01 0x00 0x0
0x20 0x0 0x01 0x00 0x1
# xm list --long vm1
(domain

)
