I’m trying to extend my working DomU config for a running IPfire 2.25 (x86_64) - Core Update 152 Xen hvm DomU with 2 NIC via pass-through and one bridge - with a second bridge.
With this I’m getting the following qemu log entry
“qemu-system-i386: -device rtl8139,id=nic1,netdev=net1,mac=xx:xx:xx:xx:xx:xx: xen: failed to populate ram at 800c0000”
and the DomU start fails. This qemu error occurs with qemu-xen 4.2 as shipped with ubuntu 20.04 as well as with qemu 5.0 shipped with ubuntu 20.10.
Since I couldn’t find any working solution on the Internet to get a second bridge working on a HVM (PV’s of course not showing this issue) I’m looking for ideas how to implement an orange network without a second bridge. Current setup is:
- RED as NIC provided via pci-passthrough
- BLUE as NIC provided via pci-passthrough
- GREEN as linux bridge (xenbr0)
The idea was to have ORANGE as a second bridge (xenbr1) without any physical interface assigned.
Any ideas/suggestions are highly appreciated.
