[libvirt-users] virRandomBits - not very random
by Brian Rak
I just ran into an issue where I had about 30 guests get duplicate mac
addresses assigned. These were scattered across 30 different machines.
Some debugging revealed that:
1) All the host machines were restarted within a couple seconds of each
other
2) All the host machines had fairly similar libvirtd pids (within ~100
PIDs of each other)
3) Libvirt seeds the RNG using 'time(NULL) ^ getpid()'
This perfectly explains why I saw so many duplicate mac addresses.
Why is the RNG seed such a predictable value? Surely there has to be a
better source of a random seed then the timestamp and the pid?
The PID seems to me to be a very bad source of any randomness. I just
ran a test across 60 of our hosts. 43 of them shared their PID with at
least one other machine.

[libvirt-users] Freeze Windows Guests For Consistent Storage Snapshots
by Payes Anand
Hi,
Is it possible to freeze windows guests for a consistent storage level
snapshot.
I am using openstack icehouse on centos 6.6
Hypervisor: KVM
Libvirt: 0.10.2
Qemu: 0.10.2
Guest OS: Windows 7 and Windows Server 2008
I was able to freeze Centos guests by issuing the command:
virsh qemu-agent-command <guest_ID> '{"execute":"guest-fsfreeze-freeze"}'
For CentOS guests, I enabled access between compute nodes and guests
through a socket by setting metadata parameter, hw_qemu_guest_agent=yes for
the guest image.
And then installing qemu-guest-agent inside the guest.
What steps do i have to follow for windows ?
Regars,
Payes

[libvirt-users] HugePages - can't start guest that requires them
by G. Richard Bellamy
Hello All,
I'm trying to enable hugepages, I've turned off THP (Transparent Huge
Pages), and enabled hugepages in memoryBacking, and set my 2MB
hugepages count via sysctl.
I'm getting "libvirtd[5788]: Failed to autostart VM 'atlas': internal
error: Unable to find any usable hugetlbfs mount for 16777216 KiB"
where atlas is one of my guests and 16777216 KiB is the amount of
memory I'm trying to give to the guest.
Yes, i can see the hugepages via numastat -m and hugetlbfs is mounted
via /dev/hugepages and there is a dir structure
/dev/hugepages/libvirt/qemu (it's empty).
HugePages is big enough to accommodate the 16G i'm allocating... and
changing the perms on that directory structure to 777 doesn't work
either.
Any help is much appreciated.

[libvirt-users] virsh snapshot-create persistent through destroy(undefine)
by Yitao Jiang
Hi,
If i take a snapshot of a qcow2 image backed domain via virsh
snapshot-create domainID and I shutdown the machine (and probably destroy
the domain if virsh list still shows it running), and then undeinfed the
domain will that snapshot still exist and be active when I define and
start the domain back up?

[libvirt-users] Disk space exhaustion
by Fabrizio Soppelsa
Hello,
what happens when an instance writes data with 0% available physical
disk space, on QCOW2 images for instance, apart from destruction and
unpredictability?
I'm aware that monitoring is mandatory in production environments, but
are there other known industry tricks to deal with this? Soft/hard limit
settings, autopause/stop, or does KVM react in doing force shut down the
VM in question?
Thank you,
Fabrizio.

[libvirt-users] redistribute virtual machines from vps hosting to end users
by Vasiliy Tolstov
Hi. I need to get ability to download backups of kvm virtual machines
(raw images) to end users. Virtualbox users can import ovs images,
that i can create, but in case of linux and virt-manager - how users
can import images and simply run it?
I think about newbie linux users, that can install virt-manager under
ubuntu via graphical package manager and do some easy steps...
Can you share me info how can i do needed things ?=)Or may be some
admins/users already solve this kind of "problems"...

[libvirt-users] Windows Guest ignores CPU topology settings on Ubuntu Lucid host
by Karol Jędrzejczyk
I try to assign 8 host cores to Windows 2003 Server Standard guest.
Because this OS version has a limit of 4 sockets, I have to change the
CPU topology. My guest definition:
<vcpu>8</vcpu>
<cpu match='minimum'>
<model>core2duo</model>
<topology sockets='4' cores='1' threads='2'/>
</cpu>
doesn't work as expected. I should have 4 CPUs in the Device Manager and
8 CPU charts in Task Manager, but I have the opposite. And no matter
what numbers I set in the topology, the guest always detects 8 sockets.
What am I doing wrong?

[libvirt-users] Port mirroring with sr-iov
by Yaron Illouz
Is it possible to do port mirroring while using sriov in the same host
and in different host
I am using libvirt
What must i do? Perhaps bridge two controller virtual function
If yes, should I do it with ovs-vsctl, or there is a libvirt
functionnality
libvirt version: 0.10.2, package: 29.el6_5.12

Re: [libvirt-users] Sr-iov passthrough - no packet arrive to guest
by Yaron Illouz
I can see from different post that if working with sr-iov, i should work
with vlan
Is this an obligation to work with vlan if working with sr-iov?
If not according to which parameter will the different vf get the
traffic.
Let's say i declare max_vfs=7, how will the traffic be seperated between
the vm?
However till i get an answer i tried to work with vlan
And i still don't get traffic in vm, but i see packet arriving in the
physical interface of the host
I tried to do the following to define the vlan
In virsh edit
<interface type='hostdev' managed='yes'>
<mac address='52:54:00:60:7f:57'/>
<source>
<address type='pci' domain='0x0000' bus='0x15' slot='0x10'

Subject: Sr-iov passthrough - no packet arrive to guest
Hi
I am trying to do passthrough to guest using sriov and libvirt
I tried to use both techniques from here
http://wiki.libvirt.org/page/Networking#Assignment_with_.3Chostdev.3E
<http://wiki.libvirt.org/page/Networking#Assignment_with_.3Chostdev.3E>
Assignment from a pool of SRIOV VFs in a libvirt <network> definition
Assignment with <interface type='hostdev'> (SRIOV devices only)
<network>
<name>passthrough-eth6</name>
<forward mode='hostdev' managed='yes'>
<pf dev='eth6'/>
</forward>
</network>
I launch the vm, there is a vm with virt-install .... --network
network=passthrough-eth6
I inject traffic with a generator so I defined it in promisc mode
without an ip address.(ifconfig eth6 promisc up)
In my physical device eth6 i can see RX increasing. But in the guest
side nothing arrive in the RX? Why?
I don't know in which log to look at to understand the problem
I defined the network-script/eth1 file in the guest is defined as
static (not dhcp) as the interface it is connected to in host have no
ip.
I have a another interface on the host connected via ovs and libvirt and
it is working fine - you can see it in log as vnet0(thanks to this
mailing-list help).
In the guest part I attached the log but I think interesting part is
Jan 27 17:03:21 localhost kernel: ixgbevf 0000:00:04.0: NIC Link is Up,
10 Gbps
I also attached dmesg output from guest
Here is the log from the host side, I can't see an error.
