Nested KVM issue
Reports posted look good for me. Config should provide the best available performance for cloud VM (L2) on Compute Node. 1. Please, remind me what goes wrong from your standpoint ? 2. Which CPU is installed on Compute Node && how much RAM ? Actually , my concern is :- Number_of_ Cloud_VMs versus Number_CPU_Cores ( not threads) Please, check `top` report in

Nested KVM issue
I would attempt to decrease number of VCPUS allocated to cloud VMs. Say try 4 => 2 . My guess there is not enough VCPUs to run OS itself. I also guess CPU model << Haswell. Please , confirm ( or not) if possible. Since Haswell was launched via my experience Intel Xeons based on this kernel (or latter kernels ) behaves much better then SandyBridge or IvyBridge based.

Strange QoS behavior
Hi, I'm having some weird problem with the setup of the QoS on a bridged network. As the docs states, outbound/inbound average speed should be expressed in KBps (KBytes per second) but in order to get a maximum speed of 10Mbps (megabits per second) surprising enough I have to use 2560 on the guest (not 1280 as expected). Using 1280 units I get a speed og 5Mbps. I'm aware of peak and

changing pci addr of SCSI storage controller: Red Hat, Inc Virtio block device (rev 01)
Greetings, when execute lspci inside my vm linux guest, I see this: :/# lspci | grep -i scsi 03:00.0 SCSI storage controller: Red Hat, Inc Virtio block device (rev 01) I don't see any such address in my xml file, is it possible to move that controller to another pci addr? Thanks, Dagg.

[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>

[virtual interface] detach interface during boot succeed with no changes
Hi guys, when I detach an interface from vm during boot (vm boot not finished), it always fail. I'm not sure if there is an existing bug. I have confirmed with someone that for disk, there is similar behavior, if this is also acceptable? # virsh destroy rhel7.2; virsh start rhel7.2 ;sleep 2; virsh detach-interface rhel7.2 network 52:54:00:98:c4:a0; sleep 2; virsh dumpxml rhel7.2 |grep

F20 Virt-Manager with MacVTap not working
Hello, I've setup a VM with default networking (NAT) and this works fine but hosts on my LAN can't get to the VM since it uses NAT. When I try to set network to use MacVTap with either default or bridged I get no networking for the VM. Any hints around this? I would like to have the VM's on the same LAN as my host and other machines. I don't care if the VM host can't reach the

dumpxml and edit the vm xml are not match.
I use vnc with password for the vm graphics, it works well. When I want to dump the xml of the vm, I found that the dumped xml does not contains the password properties in the graphics node. But when I use virsh edit to check the xml of the vm, I found the password is displayed. It's it a bug or it's just what libvirt designed to perform. -- Focus on: Server Vitualization, Network

Re: Need to increase the rx and tx buffer size of my interface
Hi Ashish, I have tested with your xml in the first mail, and it works for rx_queue_size(see below). multiqueue need to work with vhost backend driver. And when you set "queues=1" it will ignored. Please check your qemu-kvm-rhev package, should be newer than qemu-kvm-rhev-2.9.0-16.el7_4.2 And the logs? tx_queue_size='512' will not work in the guest with direct type interface,

Libvirt "tc ingress qdisc" automatically removed by ovs vlan tag setting, how?
With outbound QoS setting in Libvirt XML, libvirt will add a tc ingress qdisc for traffic shaping. Then if you set VLAN tag to that tap device, this qdisc will automatically gone by no reason. Could anyone shed some lights where should I look into? I'm really confused and got no clue here. Thanks! Steps to reproduce -- # virsh start instance-name # virsh dumpxml instance-name ...

virtual drive performance
Hi, I'm investigating a performance issue on a virtualized windows server host that is run on a ubuntu machine via libvirt/qemu. While the host can easily read/write on the raid drive with 100Mmb/s as observable with dd, the virtualized windows server running on that host is barely able to read/write with at most 8Mb/s and averages around 1.4Mb/s. This has grown to the extent that the
