Re: [Xen-users] kernel parameter for multiple pci hide?

[Christian Holpert <christian@xxxxxxxxxx>]

my grub.cfg lists:

module  /kernel-5.3.7-xen0 placeholder root=/dev/sda3 ro
init=/lib/systemd/systemd xen-pciback.hide=(04:00.0)(00:14.0)
rootfstype=ext4 [...]

xen ~ # dmesg|grep pcib
[    0.000000] Command line: placeholder root=/dev/sda3 ro
init=/lib/systemd/systemd xen-pciback.hide=(04:00.0)(00:14.0)
rootfstype=ext4 net.ifnames=0 reassign_resources noirqdebug
[    6.581153] Kernel command line: placeholder root=/dev/sda3 ro
init=/lib/systemd/systemd xen-pciback.hide=(04:00.0)(00:14.0)
rootfstype=ext4 net.ifnames=0 reassign_resources noirqdebug
[    7.360586] pciback 0000:00:14.0: seizing device
[    7.360622] pciback 0000:04:00.0: seizing device

xen_version  is 4.12.1

perhaps your syntax is just incorrect: (01.00.1) instead of (01:00.1).

Christian
