Hello, In one of my experiment, I am building a Linux VM with Network interface model as "vmxnet3". I am able to create the VM successfully, but I see that the driver loaded is "vif" and not "vmxnet3". I am using the following option for the network interface: vif = [ 'type=ioemu, mac=00:16:3e:00:00:22, bridge=xenbr0, model=vmxnet3' ]
I tried with model as e1000 and it works fine. Lspci command also does not show vmxnet3. Though, qemu device help shows that "vmxnet3" is supported on XEN 4.4.1 version I am using. I tried searching on internet about the right configuration for vmxnet3 with XEN, but not able to find right information. Can someone please help me on how to create a VM with vmxnet3? This experiment I am doing to compare the difference between vmxnet3 bandwidth on VMWARE ESXi vs. XEN Server. My sample VM configuration file is: # This configures an HVM rather than PV guest builder = "hvm" # Guest name name = "rhel-vmxnet3-xen-2.hvm" # 128-bit UUID for the domain as a hexadecimal number. # Use "uuidgen" to generate one if required. # The default behavior is to generate a new UUID each time the guest is started. #uuid = "XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX" # Enable Microsoft Hyper-V compatibile paravirtualisation / # enlightenment interfaces. Turning this on can improve Windows guest # performance and is therefore recommended #viridian = 1 # Initial memory allocation (MB) memory = 8192 # Maximum memory (MB) # If this is greater than `memory' then the slack will start ballooned # (this assumes guest kernel support for ballooning) #maxmem = 512 # Number of VCPUS vcpus = 8 # Network devices # A list of 'vifspec' entries as described in # docs/misc/xl-network-configuration.markdown vif = [ 'type=ioemu, mac=00:16:3e:00:00:22, bridge=xenbr1, model=vmxnet3' ] # Disk Devices # A list of `diskspec' entries as described in # docs/misc/xl-disk-configuration.txt disk = [ '/root/rhel_6_4/rhel-vmxnet3-xen-2.img,raw,xvda,rw', 'file:/root/rhel-server-6.4-x86_64-dvd.iso,hdc:cdrom,r' ] boot='cd' # Guest VGA console configuration, either SDL or VNC # sdl = 1 vnc = 2 Thanks, -Upanshu Upanshu Singhal EMC Data Storage Systems, Bangalore, India.
