Re: [ovirt-users] Fwd: RE: FC QLogic question

[Sander Grendelman]

This could also be an selinux issue with FC on the node, I've hit that one
before.
Especially since the luns do show up with multipath -ll
Could be as simple as flipping a sanlock related selinux boolean.

A quick test would be to boot in permissive mode.
See http://www.ovirt.org/Node_Troubleshooting#SELinux for some more
information.

That's probably not going to work as long as there is no QXL/SPICE support
for windows >= 2k12.

I also found a workaround: after disabling virtio-scsi support the

Re: [ovirt-users] ovirt guest agent iso

[Sander Grendelman]

I've tested the 3.5_5 installer on both a 2012 and a 2012 R2 guest.
On both guests the installer hung at the "installing virtioscsi" step.
Killing the installer process lead to an unbootable OS.

What is the right place to report bugs in this ISO/installer?

Re: [Users] Storage Performance Issue !

[Sander Grendelman]

You give very little information about your setup and the problem.

- What kind of storage do you use? ( software or hardware raid? how
many spindles? what kind of disks?)
- Does it have battery backed cache? Is the battery on this cache OK?
- How much IO, with how much latency, is generated on the hosts? ( run
some diagnostics e.g. "iostat -mx 10" for a couple of minutes on a
host )
- How much IO, with how much latency, is generated on the VMs?
- Is IO on the host better than on the guest? How much? (test!)
- What is the storage type of the storage domain? ( local FS? iSCSI?
Fibre Channel? GlusterFS? )
- What type of IO controller do you use in the guest? ( IDE? virtio?
virtio-scsi? )
- Do you use thin- or thick provisioned disks?
- Do you use snapshots?

The problem is that you need a different qemu-kvm package for live snapshots.
At the moment the only way to get this package is building it from the srpm:
http://ftp.redhat.com/pub/redhat/linux/enterprise/6Server/en/RHEV/SRPMS/qemu-kvm-rhev-0.12.1.2-2.415.el6_5.3.src.rpm
(It's a drop-in replacement).

This version should probably be included in the oVirt or CentOS repositories.

The VM has to be down to change the amount of memory.

This works for me in 3.3.2:

Right mouse button on VM -> Edit -> Show advanced options -> System ->
Edit Total Memory

Re: [Users] What settings are needed to run windows 98 on a VM?

[Sander Grendelman]

It looks like this (kind of) works on ovirt already.
I was able to install win98 from cdrom on a VM with IDE disk.

There are some issues:
- The VM tends to hang during boot, choosing step by step confirmation
(my first suspect was javasup.vxd) seems to fix this, this doesn't
happen if I use the "-no-kvm" option with a local kvm install.
- No network (no e1000 for win98 it seems) this can probably be fixed
with a hook to add a ne2k_pci nic
- Slow graphics, this can probably be fixed with a hook to use the
cirrus adapter in stead of qlx or vga

Working cli kvm start:
qemu-kvm -m 512 -hda /var/tmp/win98.qcow2 -no-kvm -cdrom
/var/tmp/win98se.iso -vga cirrus

Re: [Users] Making v2v easier?

[Sander Grendelman]

FWIW, importing directly from an ESX server still works:

virt-v2v-host:
- RHEL/CentOS 6.5 physical host ( virt-v2v uses qemu-kvm = extra++ slow on a VM)
- Packages:
  virt-v2v-0.9.1-5.el6_5.x86_64
  libguestfs-winsupport-1.0-7.el6.x86_64
  libguestfs-tools-c-1.20.11-2.el6.x86_64
  libguestfs-tools-1.20.11-2.el6.x86_64
  libguestfs-1.20.11-2.el6.x86_64
  virtio-win-1.6.7-2.el6.noarch ( RHEL only? )
- network acces to:
oVirt export domain (NFS)
esx host(s) to import from (HTTPS)
- virt-v2v has to run as root to mount the oVirt NFS export domain
- Edit ~/.netrc and add a line for the esx host(s) to import from
(change the <> parts):
machine  login  password 
- Fix permissions on netrc file:
chmod 600 ~/.netrc
- Run virt-v2v ( again: change the <> parts, ?no_verify=1 is needed
when esx uses self signed certs)
LIBGUESTFS_DEBUG=1 virt-v2v -ic esx:///?no_verify=1 -o
rhev -os 
--network  

Conversion can take quite some time after the disk copy,
especially when virt-v2v removes the vmware tools.
Running on a physical host (or using nested virtualization) helps.

>

Sources:
- Existing KVM (virt-manager/libvirt) platform
- ESX
- ova/ovf templates from several sources

Methods:
- KVM:
  virt-v2v with libvirtxml option, works reasonably well, most issues
are with windows guests where virt-v2v needs libguestfs-winsupport and
virtio-win (RHEL only)
- ESX:
  virt-v2v which works reasonably well _if_ the right packages
(libguestfs-winsupport virtio-win) are installed.
  virt-v2v can be used directly from ESX/ESX host (configure .netrc
first) but this is quite slow
  another option is to export the VM as an OVA and then import it with virt-v2v
- ova/ovf templates:
  hit and miss with virt-v2v, especially if they contain something
that is not a regular windows/linux guest.
  Another option is to do a direct copy of the disks on a pre-created
VM, clumsy.

Webadmin would be nice, but better behaviour from existing tools would be
a nice start too.

For example: the flow with virt-v2v is
1) Analyze source, look for disks
2) Convert/copy disks to ovirt export domain
3) Try to add virtio stuff to the copied disks on the export domain

If step 3 fails ( which happens a LOT), the copied disks are removed.
This is very frustrating if you just waited a couple of hours for a large
VM (e.g. 200GB) to be copied :(

Some kind of graceful abort/resume would be VERY welcome.

Another issue with virt-v2v is that it _always_ tries to add virtio drivers.
I have a virtual appliance that contains some kind of proprietary embedded OS:
adding drivers will always fail, give me some option to override that
and configure
simple ide / e1000 hardware for the VM

Re: [Users] get VM events via API?

[Sander Grendelman]

I did a quick test with ovirt-shell:


# Query vm id:
[oVirt shell (connected)]# list vms --query "name=testvm"

id : 8b2ad3a2-9704-47e6-99f1-f196856d7bd5
name   : plsweb02

[oVirt shell (connected)]#

# List events:

list events --kwargs "vm-id=a82874bb-152d-4efd-952b-3f3304af7bb3"

Unfortunately this uses client side filtering.

REST-API / python sdk should work similarly, AFAIK ovirt-shell uses
the REST-API too

That's also what I read but ... this presentation:

claims: "virtio-blk is about ~3 times faster than virtio-scsi in my setup" o_O

There are some interesting tests here:

Results seem to depend a lot on the guest OS IO stack/drivers (I see
you use win2k3?).

Re: [Users] Ovirt DR setup

[Sander Grendelman]

No experience there but I can make some suggestions.

The upcoming self-hosted engine feature I mentioned before should have
built-in HA for these kind of situations.
http://www.ovirt.org/Features/Self_Hosted_Engine

Another option: AFAIK oVirt engine configuration is all in the database,
configure it with an external DB and use postgres replication to have a
warm standby DB on your secondary location, combine this with
some kind of (rsync?) replication of OS/configuration.

Re: [Users] Ovirt DR setup

[Sander Grendelman]

Depending on the bandwidth/latency between the locations you could go for
replicated GlusterFS strorage and make sure that data is replicated accross
both sites. There is a self-hosted engine feature coming up, I don't know how
that will fit into replication.

Re: [Users] tuned profile for Centos hosts -- new Bugzilla or Regression

[Sander Grendelman]

I did not run into this problem at all ( neither on my cos6.4 nor on
my 6.5 hosts ).
The "virtual-host" profile was chosen automatically, installation of
vdsm was literally
as simple as adding the following lines in the %post section of my
kickstart file:

rpm -ivh http://ovirt.org/releases/ovirt-release-el.noarch.rpm
rpm -ivh 
http://mirror.1000mbps.com/fedora-epel/6/i386/epel-release-6-8.noarch.rpm

yum -y update epel-release
yum -y install vdsm

I've seen the same problems on 3.3.0 after trying to delete a snapshot.

Snapshot removal was fixed in 3.3.1, which won't help you with your
current broken snapshots.

Assigning an IP-address to a VM network in oVirt is _not_ mandatory,
it is only needed for "management" networks (ovirtmgmnt, display, storage)
where the _hosts_ need connectivity to resources on that network.

Is this a tagged or an untagged vlan? (an untagged vlan means only one vlan
per physical interface andneeds no extra configuration on the OS side)
Which other (physical) interfaces are in your "br1" interface?
Are the (tagged) vlans assigned to this interface?

A vlan interface on linux looks like this: "eth0.20" where eth0 is the
"physical" interface on which tagged vlans are configured and 20 is the
number of one of those interfaces.

In the case of an oVirt VM network the physical interface is bridged (and
sometimes bonded)
so the interface configuration looks like this: "br1.20".

The "normal" route for configuring a new network in ovirt is to configure
it in the "networks" tab
(as a VM network) and then assigin this network to physical- or bonded
interfaces on all the
hosts in your cluster.

Maybe selinux labeling?
What happens if you (temporarily!) set selinux to permissive with
"setenforce 0"?

Which user owns the file? What are the permissions on the file? And on the
rest of the iso store?
Any logging on the NFS server? Can you mount the ISO store from a different
server?

Re: [Users] Excessive syslog logging from vdsm/sampling.py

[Sander Grendelman]

The "not assigned to domain"-errors appear to be for thin provisioned disks
and for snapshots (which are also shown as thin provisioned by the engine).

One of the errors has gone away once I removed all snapshots from the VM.

Three recurring errors remain:

[root@gnkvm02 ~]# tail -n 1000 /var/log/messages | awk '/not assigned to
domain/ {print $8}' | sort | uniq -c

The first two are for the two thin provisioned disks of a VM with three
disks.
The last one is for a VM with one preallocated disk which has a snapshot.

The syslog is spammed every two seconds by these three messages.

Could it be that /dev/sda is your USB drive?
What is the output of
fdisk -l

If you've got a red-hat subscription it's in the virtio-win package in
the supplementary channel.
It looks like there's no srpm available for that one.

Two different ovirt nodes (node 1 = gnkvm01, node 2 = gnkvm02).

Configuration should be identical.
Node 1 was put in maintenance before vdsm restart.
Node 2 vdsmd was restarted without maintenance (with one running testvm).

On node1 vdsmd was restarted at 13:33
On node2 vdsmd was restarted at 13:49

I've don't have vdsm logfiles from before the problem was observed,
only syslog files.

The python SDK also uses the REST-API, the VM list is just one (fast) fetch of

https://my.engine.url/api/vms

You could parse the XML yourself but using the SDK is a lot more
generic an easier to maintain.

Re: [Users] oVirt run once Linux boot options

[Sander Grendelman]

I don't know if that's a (current) feature.
The host would have to fetch the kernel and initrd from a remote server
and then boot the VM with those files.

It seems like the current feature can use files on an iso ( e.g.
iso:///images/pxeboot/initrd.img )
and maybe local (on the node) files?

We use a seperate "linux install" network with a dhcp/tftp/pxe server
for kickstart deployments. (you could use cobbler for that with spacewalk).
After installation we change the guest network to the final config.

I can confirm that the Solaris 11 iso also fails (panic) on my Opteron
G3 cluster (Opteron 8354 cpus).
Tried with and without:
- nested virt extensions.
- realtek or e1000 nic
- memory balloon

I also tried the workaround as mentioned in
http://docs.oracle.com/cd/E27300_01/E27307/html/vmrns-bugs.html#idp1175312
no luck.

Looks like a kvm-on-amd bug.

[Users] Excessive syslog logging from vdsm/sampling.py

[Sander Grendelman]

The syslog on my ovirt nodes is constantly logging errors from sampling.py:

These messages might have something to do with reading
information/statistics through the API.
But I've stopped all my (monitoring) processes using the API.

Restarting ovirt-engine and vdsm did not resolve the issue.

Both nodes and engine server are running oVirt 3.3.1 on CentOS 6.4

This may be a red herring but the values  of disk statistics read
through the API are "static"/unchanging.

Any clues on whether these messages are serious and any ideas on how
to stop them
spamming my system logs?

qemu/libvirt "kind of" supports it (at least in F19).

In virt-manager you can define "current" and "maximum" memory allocation.

The VM only sees the current allocation and you can hot add memory up
to the maximum allocation.

The above rules might break after a reboot.

Best practice is to set the normally dynamic nfs ports to fixed
values in /etc/sysconfig/nfs and then open those ports in the firewall.

Are you doing this on a node or on your engine server?

The engine-setup configured both /etc/sysconfig/nfs and iptables for me
on my engine server (for the iso domain).

Re: [Users] Abysmal network performance inside hypervisor node

[Sander Grendelman]

I'm just wondering if the tested interfaces are bridged because I've
seen some issues with
network througput and bridged interfaces on my local system (F19).

Basically, if an IP is configured on the bridge itself ( in oVirt this
is the case if the network
is configured as a VM network ) latency goes up and throughput goes down.

Can you rule this one out by using an unbridged interface?

The main problem in oVirt with this strategy would be the lack of live
snapshot deletion.
Having to shut down the VM to delete/merge a snapshot is not nice :(

Hi Doron,

The user I've defined in [1] works for me.
A built-in login-/read-only role would be nice,
but it's quite easy to define a custom role so
more of a nice-to-have instead of a must-have.

Thanks for asking!

At the moment: both. The problem with using Nagios scripts in Zabbix is that
the trigger/alarm decision is made in different places. In Nagios this is done
in the check scripts / on the "client" side while Zabbix mainly
collects data and
fires triggers if certain conditions in that data are met.

New(er) Zabbix versions also have a feature called "low level discovery" that
automatically creates items.

It also seems that there is better RESTful/ovirt API support in python
so I'm giving
that a try too. Although perl is usually my poison of choice too ;)

Thanks for the info I'll look into this.

It does make the logic in the script a bit harder because you have to store
the sessionid somewhere and check if the session is still valid.

[Users] API read-only access / roles

[Sander Grendelman]

I'm working on (Zabbix) monitoring through the RESTful API.

Which role should I assign to the monitoring user?

The user only needs read access to the data but it looks like
I nead to assign at least an "Admin" role to the user to be
able to read data through the API.

For this I've created a "AdminLoginOnly" role that only has
System->Configure System->Login Permissions access.

Is this the way to go for this king of configuration? Or is there
a way to further minimize the permissions of this user?

Another issue is that a "Login" event is generated every time
the user connects through the API. This makes the "Events"
pane less useful / readable. Is there a way to disable this for
some users/roles?

Yes, It's probably going to take a bit of a hack to make this
work with the current mechanism/gui because the key file
has to be an actual _file_.

I just made a local config + keyfile for my testnodes.

Yes that's what I did. One of the problems with that is that
port= maps to the sshport field in the apc part of the gui
which brings us back to BZ 1014513.

Re: [Users] Fence-virt support

[Sander Grendelman]

It "kind of" worked.

I did an insert into the database to add an "xvm" fence mode.
After that I had to first change the mode to ipmilan to get
rid of a couple of mandatory fields. The setup also breaks
when I try to edit a host.

The fence mechanism makes a couple of assumptions that
don't work with fence-virtd:

- fence-virtd uses a keyfile, no username and password.
- fence-virtd uses port=vmname to identify a VM

The gui has mandatory username and password fields and
the standard port/sshport field only takes numeric values.

Some of the problems I ran into are probably related to
https://bugzilla.redhat.com/show_bug.cgi?id=1020344

Re: [Users] Fence-virt support

[Sander Grendelman]

I'm running an ovirt environment (two virt hosts and one engine host)
on libvirt/kvm on fedora 19. (nested KVM).

I want to fence the virtualized virtualization hosts from the engine host
(or their partner host) through libvirt. Fence-virt can do this.

I know this is a bit of a niche case, but it's very useful for testing/demo
purposes.

[Sander Grendelman]

Snapshot deletion on preallocated FC domain disks is broken in ovirt-stable/3.3

Both online and offline snapshot deletion leads to an error and the
snapshot state is changed to "BROKEN".

When I apply the patch at http://gerrit.ovirt.org/#/c/19983/ from

works again.

I'm currently building a ovirt test-environment using nested
virtualization on libvirt/kvm.

For the most part this works great. However, I can't configure
fencing/power management
because only hardware BMC's/fencing devices are supported.

Is this something that could/should be included in a future oVirt version?

Re: [Users] Live storage migration snapshot removal (fails)

[Sander Grendelman]

I can open a bug on this.

Should I file it for the entire "snapshot removal fails"-problem or
just this error?


I've looked at the parsing error and the problem seems to be that the
qemuImg.check() function expects a qemu-img version that outputs a
string like: "Image end offset: 262144".

The only version I could find that does that is the one in the F19 virt-preview
repository. Stock F19 qemu-img doesn't have this output. Nor do the stock EL6
or qemu-img-rhev EL6 versions.

The only function that calls qemuImg.check is blockVolume.shrinkToOptimalSize()
this function needs (and uses) the parsed offset to shrink the LV containing the
qcow2 image.

That's the way it worked for me.

- Put one host in maintenance
- Install *-rhev packas on that host
  yum localinstall qemu-*rhev*.rpm)
  this replaces the regular packages:
  Nov 06 16:15:38 Installed: 2:qemu-img-rhev-0.12.1.2-2.355.el6.9.x86_64

- Restart vdsm, enable host migrate test VM to host, test live storage
migration: OK
- Put host back in maintenance and reboot.
- Activate host and repeat maintenance/installation steps with other hosts.

The "solution" for the live snaphost problem as proposed in
https://bugzilla.redhat.com/show_bug.cgi?id=1009100 is:

 |BZ| Vdsm should check (hopefully via libvirt) if the underlying
qemu supports live snapshot, and report this feature to Engine.
 |BZ| If it does not, block this feature in UI.

That is something that should be implemented, however,  there should
also be some way to use a full-featured kvm with oVirt.

Can oVirt carry the qemu-*rhev* packages?
Or is this something that should be in epel? Or CentOS?

I can confirm that live storage migration works with qemu-kvm-rhev.

For my test I have built the package using

qemu-kvm:

[Users] Live storage migration fails on CentOS 6.4 + ovirt3.3 cluster

[Sander Grendelman]

Moving the storage of a (running) VM to a different (FC) storage domain fails.

Steps to reproduce:
1) Create new VM
2) Start VM
3) Start move of the VM to a different storage domain

When I look at the logs it seems that vdsm/libvirt tries to use an
option that is unsupported by libvirt or the qemu-kvm version on
CentOS 6.4:

"libvirtError: unsupported configuration: reuse is not supported with
this QEMU binary"

Information in the "Events" section of the oVirt engine manager:
