I have a libvirt (libvirtd 3.0.0) install with several guest VMs all under kvm. I'm using bridged networking on the host to allow them full access to the networks. The host OS is Debian (stretch).
auto br0 iface br0 inet static bridge_ports eno1 bridge_stp on bridge_waitport 0 bridge_maxwait 0 address [redacted] netmask 255.255.255.0 gateway [redacted] dns-nameservers [redacted]
I just installed a Windows 10 Pro VM (Version 1809, build 17763.379) which does not seem to be able to access the network. The Windows interface troubleshooter shows no problems with the "hardware" but it's unable to ping the default gateway (same subnet as the host OS).
The host and my other guests are all dual-stack, but for the moment I'm only attempting to configure the Windows guest with IPv4.
My VM's network interface configs are thus:
<interface type='bridge'> <mac address='52:54:00:f7:46:de'/> <source bridge='br0'/> <model type='rtl8139'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x03' function='0x0'/> </interface> <interface type='bridge'> <mac address='52:54:00:f9:0c:28'/> <source bridge='br1'/> <model type='rtl8139'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x04' function='0x0'/> </interface>
The OS driver matches the driver listed in the VM's XML definition.
What should I be looking at?
