Hi,
I have no experience with KVM/QEMU virtualization software as this is my first attempt to set up a VM using this suite. I succeeded setting up VGA pass-through but I am really struggling with an unexpected issue: trying to set up bridged networking using virt-manager. For a reason I cannot identify the guest OS cannot connect to the network.
The host OS is Fedora 23 (up to date packages), the guest OS is Windows 10 1511, virt-manager 1.2.1.
The listing of network interfaces on the host:
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: eth0: <BROADCAST,MULTICAST,SLAVE,UP,LOWER_UP> mtu 9000 qdisc mq master bond0 state UP mode DEFAULT group default qlen 1000
link/ether f8:32:e4:72:63:e6 brd ff:ff:ff:ff:ff:ff
3: eth1: <BROADCAST,MULTICAST,SLAVE,UP,LOWER_UP> mtu 9000 qdisc fq_codel master bond0 state UP mode DEFAULT group default qlen 1000
link/ether f8:32:e4:72:63:e6 brd ff:ff:ff:ff:ff:ff
4: br0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 9000 qdisc noqueue state UP mode DEFAULT group default
link/ether f8:32:e4:72:63:e6 brd ff:ff:ff:ff:ff:ff
5: bond0: <BROADCAST,MULTICAST,MASTER,UP,LOWER_UP> mtu 9000 qdisc noqueue master br0 state UP mode DEFAULT group default
link/ether f8:32:e4:72:63:e6 brd ff:ff:ff:ff:ff:ff
6: virbr0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc noqueue state DOWN mode DEFAULT group default
link/ether 52:54:00:99:f8:1b brd ff:ff:ff:ff:ff:ff
7: virbr0-nic: <BROADCAST,MULTICAST> mtu 1500 qdisc fq_codel master virbr0 state DOWN mode DEFAULT group default qlen 500
link/ether 52:54:00:99:f8:1b brd ff:ff:ff:ff:ff:ff
13: vnet0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 9000 qdisc fq_codel master br0 state UNKNOWN mode DEFAULT group default qlen 500
link/ether fe:54:00:1e:3f:a8 brd ff:ff:ff:ff:ff:ff
The physical NIC cards in the host:
00:1f.6 Ethernet controller: Intel Corporation Ethernet Connection (2) I219-V (rev 31)
0b:00.0 Ethernet controller: Intel Corporation I211 Gigabit Network Connection (rev 03)
Host IP is 192.168.1.111 (on br0).
Virtual Network Interface details in virt-manager:
Network source: Bridge br0: Host device bond0
Device model: virtio
MAC address: 52:54:00:1e:3f:a8
Network setup on guest:
IP: 192.168.1.160
Netmask: 255.255.255.0
Gateway: 192.168.1.1
DNS: 192.168.1.1
NetKVM driver is installed on guest (from virtio-win-0.1.112.iso).
The network icon in the guest has an exclamation mark saying No internet connection. The IP setup on guest is manual (DHCP also not working). The only machine responding to ping from the guest is the host (192.168.1.111).
Firewall is disabled on host and guest, SELINUX is disabled on host. I tried the other device models available in the virt-manager - e1000 and rtl8139 - but none of them work.
Does anyone have an idea on what to check or what would be a list of checks in order to identify the issue?
Thank you,
Paul
