My mobo is rev.2, firmware 2901 I used (ivrs_ioapic[7]=00:14.0 ivrs_ioapic[8]=00:00.2). I am not using anymore and my qubes 4.0 is working fine. But ubuntu forum has a solved solution with different ioapic: Quick solution for Sabertooth 990FX (R1.0): Edit file /etc/default/grub, find line "GRUB_CMDLINE_LINUX_DEFAULT=", edit it to look like: Code: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash ivrs_ioapic[7]=00:14.0 ivrs_ioapic[8]=00:00.1" There are iommu info here too: from Xen https://wiki.xen.org/wiki/VTd_HowTo If you can not solve the iommu problem, change all vms to PV. Maybe this is the cause of libxenlight error. Change all vms to PV, including sys-net. Later I will send you the commands to start networking. -- You received this message because you are subscribed to the Google Groups "qubes-users" group.
