Thanks Wangkai but libvirt infact pre-configures network tap devices and pre-opens /dev/vhost-net file and passes these to qemu as open, ready to use file descriptors. My issue is that my qemu requires that /dev/vhost-net directory is removed and it's kernel module be unloaded. Then it creates a vhost -net d...

I am using a custom qemu to launch a vhost enabled VM. The qemu doesn't use the default "/dev/vhost-net" directory as character device. Due to this I am getting the error: qemu-system-x86_64: -netdev type=tap,id=net1,script=no,downscript=no,ifname=port3,vhost=on: vhost-net requested but could not be initialized ​Is there a way to tell libvirt to ​avoid using the default

Hi, When I use 'virConnectOpenAuth' function to connect to '192.168.1.102' libvirtd with ssh, Code below, the screen print the dialog "root at 192.168.1.102's password:" , and only After I type the password, the connection can be created. How can I connect to libvirtd with ssh automatically? No need to type the password manually. char *au[2] = {"root",

...off,guest_ecn=off ​ As you can see I have created tap interfaces port3 & port4 and I just want to connect the VM to these VMs. On 24 July 2014 13:31, Daniel P.

Hi all, When I defined a network use the host bridge "virbr1" an error occurred : "libvir: error : Unable to create bridge virbr1: File exists" But how can I define this network use the host bridge "virbr1" ? <network> <name>def1</name> <bridge name='virbr1'/> <forward mode='nat'> <interface dev='eth0'/>

Hi all, I try to get vm cpu stat by function "virDomainGetCPUStats", when the vm Cpu usage is 100%, I can see from the vm shell by "top", when the info Get by the "virDomainGetCPUStats" show only the "cpu_time" increased, "user_time" and "system_time" was not changed at all. Is that correct ? How can I get the vm cpu usage?

For qemu, the default vhost drive file is “/dev/vhost-net”, when you configured vhost on. Give the command “modprobe vhost-net” to add host kernel support for vhost. This is cannot controlled by libvirt I think.

Hi, Dear Madam/Sir Can you check for me whether the Openssh bugID 370 has been resolved or not. If so, can you provide me the solution? Looking forward to your reply. Thank you very much. Regards Wang Kai
