How to set the MTU size of VM interface
Dear all:
I start a VM with MTU size 1450, and login VM to check the mtu size, but this setting didn't work.
The VM xml is like this:
<interface type='bridge'>
<mac address='52:54:00:54:14:f8'/>
<source bridge='ovsbr1'/>
<virtualport type='openvswitch'>

create vm timeout
Hi all:
I create VM on most hypervisors very quickly, about 2 seconds. But some hypervisors are slow, taking more than 10 seconds. I started the debug log for libvirtd and found that some threads had timed out. Thread 95205 has two 5-second timeouts, but I don't know why?
Below some information about my hypervisor:
[root@node1 datapool]# virsh -v
3.4.0
[root@node1 datapool]# qemu-x86_64

I want to auto-hotplug usb devices by using libvirt.
Bellow the call of libvirt:

I think it's a bug, when call virDomainGetState after "service libvirtd stop", I receive signal SIGPIPE.

I'm facing problems trying to define a bridge on Ubuntu 16.04, using libvirt 3.4.0.

Re: Create virtual machine failed using virDomainCreateXML
Dear Michal:
I'm sorry. The pasting XML I described earlier is wrong, and the real thing is:
<interface type='bridge'>
<mac address='52:54:00:0a:2b:2a'/>
<source bridge='lcs_br_1'/>
<virtualport type='openvswitch'/>
<bandwidth>

[qemu-kvm] Network bandwidth limits via libvirt
Hi all,
I try to understand why the network bandwidth limits are not applied to my ubuntu 16.04.2 VM (qemu-kvm driver) and I would need some insights.
I create my VM network with virsh and when I issue a dumpxml on my network, I can see that bandwidth limits are set:
virsh # net-dumpxml nat_limit
<network>
<name>nat_limit</name>

libvirt call qemu to create vm need more than 10 seconds
Hi all:
It takes more than 10 seconds to create a vm on a Dell R830 machine, but it takes less than 2 seconds on other machines. This is not normal, so I turned on the debug log for libvirtd. I analyzed the log and found that the time was spent on libvirtd calling qemu. Thread 95225 calls the qemuProcessLaunch interface at 14:22:30.129 and then builds the emulator command line, but the
