bridge + SR-IOV guests with KVM
Hi,
I managed to get SR-IOV with an Intel I350 NIC to work.For this I
followed the documentation on this page:
https://wiki.libvirt.org/page/Networking#Assignment_from_a_pool_of_SRIOV_VFs_in_a_libvirt_.3Cnetwork.3E_definition
But as I have more VMs then VF on the NIC I also have a bridge wich
serves the other guests. As I run Debian Buster as host I followed the
documentation here:

Re: SR-IOV Pool Availability
I have an Intel X540 SR-IOV NIC in a box with ACS support running RHEL6.4.
Hi Hongming, I'm hoping you can please help with two issues:
1. The pool works, but I transparent VLAN with the pool does not. I
have to manually run "ip" afterwards to get it to work.

SR-IOV pool with static MAC address and vlan
I'm planning to set up a libvirt/kvm system using a card with SR-IOV
support. I'd like to use the vf pool option rather than statically
assigning a vf to each vm. However, I'd also like each vm to have a
static MAC address and I have multiple VLANs they will be on.
I found in the documentation a syntax for specifying a MAC and a vlan
when the vf is statically assigned, but I don't

connecting host and guest vm using a dummy nic
Greetings all,
I have a host machine that runs a router within a vm.
I want to allow a connection between the host and the guest so the host can connect to the lan provided by the router vm.
I've created a dummy interface with these commands:
$ ip link add ens99-dummy type dummy
$ ip link set ens99-dummy address 52:54:00:1f:d0:ff
this resulted with this output:
$ ifconfig ens99-dummy

POOL of SRIOV networks with multiple PFs
We are using an Intel 82599 chip that allows 4 PFs ( eth0..3) per VM. I am able to manually start VMs using the hostdev

The entire point of qemu-bridge-helper is that it can be run by
non-privileged users, but once run it has root privileges. This is done
by the binary having the "suid bit" set. If your distro

Re: qemu-bridge-helper issue
HI Laine,
Looks like we are able to run qemu-bridge-helper and it internally tries to
create tap interface.
While creating this tap interface we are getting Operation not permitted
error:
* failed to create tun device: Operation not permitted*
How we can create tun interface without root user is the issue. Please let
us know how to proceed on this.

SR-IOV pool with static MAC address and vlan
Hi Paul,
You can set the static MAC address and VLAN in the interface section of the
VM xml.
So it will not change even when the VM shuts down and restarts.
VM interface xml:
<interface type='network'>
<mac address='52:54:00:85:e2:cd'/>
<source network='hostdev_net'/>
<vlan>
<tag id='42'/>
</vlan>

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,

Delete user data from Dovecot server
Hello,
I'm testing Dovecot 2.0.
I plan to use Dovecot 2.0 with thousands of domains per server. My user
base is under virtual MySQL.
when I add a user in the database, it is automatically created in the
structure of Dovecot at first login.
Is there a easy way to delete a user ?
Thank you.

Re: Need to increase the rx and tx buffer size of my interface
Hi Ashish,
IMO, it is yes, no way to increase tx_queue_size for direct type interface
