Re: [Xen-users] pcifront problem in Ubuntu 10.04 domU

[Francisco Barrera <francisco.barrera@xxxxxxxxx>]

Hello Mark,
I've installed linux-image-virtual with command "sudo aptitude install linux-image-virtual" and updated grub, but after rebooting, the pci device doesn't appears (lspci).
I've seen the dmesg log and nothing about pci frontend devices.
