Subject: [Xen-devel] hide pci device issue.
Sorry to post here, should I ask question about xen here?
if a PCI device is hided via domain0 kernel startup parameter, should it be seen in domain 0's lspci command output?
Below is my grub startup parameter. xen-pciback.hide=(00:02:0)(00:02:1) is used to hide two device.
kernel /xen.gz dom0_mem=1024M cpufreq=xen dom0_max_vcpus=1 dom0_vcpus_pin iommu=1
module /vmlinuz-3.10.7-1.el6xen.x86_64 ro root=UUID=90faade6-ee45-499c-88a0-a460ae727270 rd_NO_LUKS rd_NO_LVM LANG=en_US.UTF-8 rd_NO_MD SYSFONT=latarcyrheb-sun16 KEYBOARDTYPE=pc KEYTABLE=us rd_NO_DM rhgb quiet
xen-pciback.hide=(00:02:0)(00:02:1)
In my understanding, the two devices shouldn't be used by domain 0. lspci cannot see the two device.
but lspci still can see the two device. is there misunderstanding for me ?
