What is virtio driver?
VirtIO drivers are paravirtualized device drivers required for Microsoft Windows virtual machines to run in container-native virtualization. The supported drivers are available in the container-native-virtualization/virtio-win container disk of the Red Hat Container Catalog.
What is Nic QEMU?
The nic option enables the network card in the guest. The user option sets up a virtual NAT’ted subnet, with a DHCP server started by qemu that gives out (usually) 10.0. 2.15 to your guest and puts the host on 10.0.
How do I get internet on QEMU?
Connect QEMU VM to Internet with bridge helper
- (1) Create a bridge $ sudo ip link add br0 type bridge.
- (2) Bind a physical NIC to the bridge $ sudo ip addr flush dev eno2 $ sudo ip link set eno2 master br0 $ brctl show bridge name bridge id STP enabled interfaces br0 8000.1866daf9a071 no eno2.
- (3) Set up br0.
What’s the difference between VirtIO and RTL8139?
Googling “virtio vs e1000 vs rtl8139” didn’t help much. The first two pages of results are filled with official documentation, which doesn’t say much, and the blog posts which boil down to “use option N, because I tried it and it’s great.”
Which is better E1000 or VirtIO PCI?
I expected to see much higher throughput in case of virtio-pci compared to e1000, but they performed identically. Test with virtio-pci ( 192.168.0.126 is configured to T60 and 192.168.0.129 is configured to PC1 ): Test with e1000 ( 192.168.0.126 is configured to T60 and 192.168.0.129 is configured to PC1 ):
Which is better RTL8139 or E1000?
The discussion seems to imply that e1000 was at some point preferred to rtl8139, but doesn’t tell why.
Which is easier to emulate Intel E1000 or Realtek 8139?
Realtek 8139 apparently is pretty simple, hardware-wise, so it may be comparatively easier to emulate in a VM than Intel e1000. But on the other hand, the simplicity also means the operating system inside the VM may need to do some extra work to satisfy the conditions of the NIC emulation when the actual host NIC could do some of it in hardware.
