[libvirt-users] Configure QCow2 L2 Cache through virt domain XML
by Stefano Bonicatti
Hello, i was wondering if it is possible to configure the l2 cache of a
qcow2 image through the domain xml.
I cannot find any documentation about it... the only thing i've found is
that i can pass custom options to qemu command line through the
<qemu:commandline> tag, but, to my understanding, that would mean entirely
remove the <disk> tag for the image and rewrite it as a list of args for
the command line.
Isn't there an easier way?
An example of what i'm speaking about
is: file=hd.qcow2,l2-cache-size=4194304,refcount-cache-size=262144

[libvirt-users] Getting "unknown device type" when attaching NPIV (vHBA) to vm
by Vaknin, Rami
Hi,
I'm trying to attach a host FC HBA to VM (NPIV).
Running ovirt 3.5 on CentOS 6.7, libvirt-0.10.2-46.el6_6.6.x86_64, I created vHBA using nodedev-create command - see below HBA and vHBA.
I wrote a vdsm hook which appends the vHBA xml stanza to the devices xml element but the vm start starts without the vHBA device.
Also, when trying to attach the device manually as a live device - I get:
2016-02-01 21:30:24.216+0000: 129764: debug : qemuDomainObjBeginJobInternal:847 : Starting job: modify (async=none)
2016-02-01 21:30:24.216+0000: 129764: error : virDomainDeviceDefParse:8136 : XML error: unknown device type

[libvirt-users] Domain cannot talk to itself unless virbr0 is in promiscuous mode
by David Raison
Hi
We have the following situation:
A hypervisor using KVM-Qemu/libvirt with a single VM. The VM has the
internal IP 192.168.122.151 on the default network pool using virbr0 on
the hypervisor.
We've set up netfilter rules to DNAT requests on one IP of the
hypervisor to the VM. So, first of all, forwarding to the internal IP
range is allowed:
> $IPTABLES -I FORWARD -m state -d 192.168.122.0/24 --state
> NEW,RELATED,ESTABLISHED -j ACCEPT
Then we're forwarding a few ports from the hypervisor's public IP to the
VM, imaps being one of them:
> Chain PREROUTING (policy ACCEPT 2606 packets, 169K bytes) pkts bytes
> target prot opt in out source destination 142 8048 DNAT tcp -- * *
> 0.0.0.0/0 a.b.c.145 tcp dpt:993 to:192.168.122.151
Since the VM is also doing SMTP, we need it to send out mail via a
dedicated IPv4, which we achieve through the following SNAT rule:
> Chain POSTROUTING (policy ACCEPT 1121 packets, 77556 bytes) pkts
> bytes target prot opt in out source destination 81 6262 SNAT all -- *
> * 192.168.122.151 0.0.0.0/0 to:a.b.c.145
Now, on this mailserver, we're also running a roundcube instance. For
authentication, roundcube connects to the imaps port of the local
dovecot instance. In order for the SSL certificate check to succeed, it
needs to do so using the actual domain name, and cannot use "localhost"
or the loopback IP address.
The problem is that, given the above iptables rules, connecting from
inside the VM to itself via the hypervisor's external interface doesn't
work. The connection simply times out, logging reveals they're not
getting forwarded.
We've added logging to iptables and testing in promisc mode vs. not-promisc:
This is what gets logged when virbr0 is not in promisc mode:
> Feb 11 19:12:31 hyper kernel: [199815.004207] prerouting imaps:
> IN=virbr0 OUT= PHYSIN=vnet0
> MAC=fe:54:00:17:c8:2a:52:54:00:17:c8:2a:08:00 SRC=192.168.122.151
> DST=a.b.c.d.145 LEN=60 TOS=0x10 PREC=0x00 TTL=64 ID=40689 DF
> PROTO=TCP SPT=43460 DPT=993 WINDOW=29200 RES=0x00 SYN URGP=0
And this when the device is in promisc mode:
> Feb 11 19:14:33 hyper kernel: [199937.674189] prerouting imaps:
> IN=virbr0 OUT= PHYSIN=vnet0

> SPT=43461 DPT=993 WINDOW=29200 RES=0x00 SYN URGP=0
> Feb 11 19:14:33 hyper kernel: [199937.674221] forwarded imaps: IN=virbr0
> OUT=virbr0 PHYSIN=vnet0 MAC=52:54:00:17:c8:2a:52:54:00:17:c8:2a:08:00
> SRC=192.168.122.151 DST=192.168.122.151 LEN=60 TOS=0x10 PREC=0x00 TTL=63
> ID=2244 DF PROTO=TCP SPT=43461 DPT=993 WINDOW=29200 RES=0x00 SYN URGP=0
> Feb 11 19:14:33 hyper kernel: [199937.674766] forwarded imaps: IN=virbr0
> OUT=virbr0 PHYSIN=vnet0 MAC=52:54:00:17:c8:2a:52:54:00:17:c8:2a:08:00
> SRC=192.168.122.151 DST=192.168.122.151 LEN=52 TOS=0x10 PREC=0x00 TTL=63
> ID=2245 DF PROTO=TCP SPT=43461 DPT=993 WINDOW=229 RES=0x00 ACK URGP=0
Another workaround we found is to disable iptables on the bridge
interface.
> root@hyper:~# echo 0 > /proc/sys/net/bridge/bridge-nf-call-iptables
But I do not consider this a solution, merely a workaround. I
do not understand why the forward rule mentioned above does not apply to
the situation where IN and OUT are both virbr0?
Thank you for any advice,
David

[libvirt-users] Unable to create raw volume on netfs storage (Operation not permitted)
by Benjamin Weik
Hello,
we are trying to create a new setup with a centralized storage server. Currently we are running multiple "All-in-One" hosts using raw volumes stored on the local disk of the server.
I tried it first with samba but it did not work so currently I have configured it as NFS.
This is my current setup:
For Storage:
OS: Ubuntu 16.04 beta (to match vHost version),
IP: 123.123.123.2
NFS: v1.2.8
Samba: v4.3.3
For vHost:
OS: Ubuntu 16.04 beta (as the Package in Ubuntu 14.04 has still a bug that prevents mounting of samba shares)
IP: 123.123.123.3
Libvirt: v2.21
Qemu: 2.5
Both are simply connected via switched network for testing.
So on the Storage server I created a user and a group called vstorage (uid:1000,gid:500)
Then created a folder /pool owned by this user, permission 777
And exported it via nfs in /etc/exports:
/pool 123.123.123.3(rw,async,no_subtree_check,all_squash,anonuid=1000,anongid=500)
On the vHost I defined the pool via XML:
<pool type='netfs'>
<name>pool</name>
<source>
<host name='123.123.123.2'/>
<dir path='pool'/>
<format type='nfs'/>
</source>
<target>
<path>/var/lib/virt/images</path>
</target>
</pool>
When I try to define a volume in the pool, it will always fail if raw format (default) is used.
virsh vol-create-as --pool pool --name test --capacity 512M
error: Failed to create vol test
error: Failed to create file '/var/lib/virt/images/test': Operation not permitted
In /var/log/syslog I can find the following
libvirtd[889]: cannot chown '/var/lib/virt/images/test' to (0, 0): Operation not permitted
libvirtd[889]: Failed to create file '/var/lib/virt/images/test': Operation not permitted
When I try it with a different format, like qcow2 it is working fine:
virsh vol-create-as --pool pool --name test --capacity 512M --format qcow2
Vol test created
I am unable to find the reason for this problem, it also took me quite a while find out that this is a format issue as the error message is actually not really helpful.
I found a small guide on setting up KVM from IBM and they are using NFS with raw images, so I'm not sure where the error is
https://www.ibm.com/developerworks/library/l-using-kvm/
Maybe someone could shed some light on this? The same error message happens btw. with Samba.
Best regards,
Benjamin Weik

[libvirt-users] Networking with qemu/kvm+libvirt
by Andre Goree
I have some questions regarding the way that networking is handled via
qemu/kvm+libvirt -- my apologies in advance if this is not the proper
mailing list for such a question.
I am trying to determine how exactly I can manipulate traffic from
a _guest's_ NIC using iptables on the _host_. On the host, there is a
bridged virtual NIC that corresponds to the guest's NIC. That interface
does not have an IP setup on it on the host, however within the vm
itself the IP is configured and everything works as expected.
During my testing, I've seemingly determined that traffic from the vm
does NOT traverse iptables on the host, but I _can_ in fact see the
traffic via tcpdump on the host. This seems odd to me, unless the
traffic is passed on during interaction with the kernel, and thus never
actually reaches iptables. I've gone as far as trying to log via
iptables any and all traffic traversing the guest's interface on the
host, but to no avail (iptables does not see any traffic from the
guest's NIC on the host).
Is this the way it's supposed to work? And if so, is there any way I
can do IP/port redirection silently on the _host_?
Thanks in advance for any insight that anyone can share :)

[libvirt-users] GPU passthrough - MSI R9 380 4GB, works only ONCE
by David Hlacik
Hello guys,
I have a problem when using my MSI R9 380 4G graphic card as GPU
passthrough with KVM.
At the first linux boot (Fedora 23) I am able to successfully start virtual
machine and it works!
However if i will shut down virtual machine and start it again - the screen
will stay blank!
So far I have been able to find on the internet that some graphic cards
just can not reinitialize itself when there is no power off/on, which could
be the case of mine as well.
Also I am very much surprised that this graphic card has no UEFI rom!
Any help would be appreciated

[libvirt-users] route seems to be not affecting the network behavior
by pichon
Hello,
I’m trying to set a default gateway on an isolated lan (because one of my VM get access to an other lan).
I’m trying to use the option <route > but this doesn’t affect the default route on my VMs.
Here is the network xml
<network>
<name>prd-private-lan</name>
<uuid>2222222222222222222222</uuid>
<bridge name='virbr3' stp='off' delay='0'/>
<mac address='52:54:00:08:1e:d8'/>
<domain name=‘pre' />
<dns>
<forwarder addr='8.8.4.4'/>
<forwarder addr='8.8.8.8'/>
</dns>
<ip address='10.10.0.1' netmask='255.255.255.0'>
<dhcp>
<range start='10.10.0.128' end='10.10.0.254’/>
<host mac=‘xxxxxx' name=‘finternet.pret' ip='10.10.0.7'/>
</dhcp>
</ip>
<route address='10.10.0.0' netmask='255.255.255.0' gateway='10.10.0.7'/>
</network>
And here is what I get on the guest VM connected to the pre-private-lan
route
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
10.10.0.0 0.0.0.0 255.255.255.0 U 100 0 0 ens4
Can someone help me or tell me what to do ?
What I’m a bit surprise is the file //var/lib/libvirt/dnsmasq/prd-private-lan.conf doesn’t contain any clause defining the new gateway. Something like ‘dhcp-option=3,10.10.0.7'
strict-order
no-resolv
server=8.8.4.4
server=8.8.8.8
domain=prd.pipiche.net
expand-hosts
pid-file=/var/run/libvirt/network/prd-private-lan.pid
except-interface=lo
bind-dynamic
interface=virbr3
dhcp-option=3
no-resolv
dhcp-range=10.10.0.128,10.10.0.254
dhcp-no-override
dhcp-lease-max=127
dhcp-hostsfile=/var/lib/libvirt/dnsmasq/prd-private-lan.hostsfile
addn-hosts=/var/lib/libvirt/dnsmasq/prd-private-lan.addnhosts
Of course I can add an explicit route on the guest - so did I - but for maintenance purposes I would like to avoid and have all configuration in the network XML
Thanks in advance
