Hi Couple of questions around macvtap direct usage: 1) is the document here current? https://libvirt.org/formatnetwork.html#examplesDirect I have been able to get host to guest network traffic without any special configuration or switch since Fedora 28 when I first started using it. Using <forward mode=vepa> requires switch port mirroring, but just using <forward mode=bridge>

Hello, New kernel version 2.6.32-279.2.1.el6.x86_64 in combination with xorg-x11-drv-nouveau Version:0.0.16 is somehow painfully slow on my laptop. during start up it takes almost half a minute for gnome login to appear. After having logged in the following happens: - gnome top and bottom panels "slide/crawl" in to view one pixel line at a time. - starting the terminal takes much more

Hello, Is it reasonable for one CPU on the host to be loaded 20-30% on 100 mbps download in a guest? There is barely any (1-2%) load in the guest. The host is running ubuntu 18.04 on an Intel i7-7700K, virtualization etc is enabled. Everything except host load on guest network activity is fine. This is how i setup the network with virt-install: --network

The guest was setup through virt-manager. The machine is not configured much after a F20 install (I believe I didn't change any network things) Here is the network part: <interface type='direct'> <mac address='52:54:00:fe:b0:66'/> <source dev='em1' mode='bridge'/> <target dev='macvtap0'/> <model

1. Does vepa mode in libvirt use sr-iov ? 2. How can I do port mirroring with sr-iov? vepa This network uses a macvtap "direct" connection in "vepa" mode to connect each guest to the network (this requires that the physical interfaces used be connected to a vepa-capable hardware switch. The physical interface to be used will be picked from among those listed in

I am running OpenStack inside a libvirt guest that is connected to the local network via a macvtap interface. My experience so far suggests that a macvtap interface will not pass traffic with a source MAC address other than the MAC address of the interface itself...for example, if inside the guest eth0 is attached to a bridge. Is that correct, or is there some setting that will make that work?

Hi Laine, thanks for your answer, I really appreciate that.

I seem to have run into https://bugzilla.redhat.com/show_bug.cgi?id=855640, because when I tried the fix/work-around at the end (comment 11), ethtool -K eth0 gro off, my download speed by speedtest went from undetectable to ~150Mb/s. However, it was not able to connect for the upload test, and so something may still be off. Non-virtual machines can do the upload test, so it's not just a

Hi Yalan and Michal, Thank you for your response. So what I understand is that I can change rx_queue size even if I use direct type interface and qemu driver as long as the driver is virtio. Am I right? If that is the case why am I getting the error saying that error: XML document failed to validate against schema: Unable to validate doc against /usr/share/libvirt/schemas/domain.rng Extra

Hi Yalan, In the previous email you mentioned "tx_queue_size='512' will not work in the guest with direct type interface, in fact, no matter what you set, it will not work and guest will get the default '256'. " So if I am using macvtap for my interfaces, then the device type will always be direct type. Does it mean that there is no way I can increase the buffer size

Hi, I would like to run a network firewall as a VM on a KVM host. There are ~ 25 VLANs delivered to the KVM host on three dedicated links, no LACP or other things. I have the VLANs 100-180 on the host's enp1s0, the VLANs 200-280 on the host's enp2s0 and the VLANs 300-380 on the host's enp3s0. To save myself from configuring all VLANs on the KVM host, I'd like to hand the entire

I intend to realize the connection to the Internet by WLAN (at the presen time DSL cable modem). The WLAN DSL-Router should not be the problem. But which wlan- adapter (internally (PCI), USB... whatever) can be recommended for a work "out of is the box" with cent OS 5? Thx Timothy
