It's websocket proxy port, not really need there.

Network connection where? To the internet? And what do you mean by
losing it - is the network traffic choppy, or are you working via a
SPICE console and it's not responsive?...

It seems that one of your host's interfaces is heavily utilized - I'd
postulate that the VM is suffering because there's no capacity for the
traffic it's sending/receiving. What networks are attached to the most
utilized interface of the host, and is one of those indeed the network
used by the VM for its aforementioned "network connection"?

Subject: [ovirt-users] Cannot activate storage domain

Have the following:

6 hosts – virt + Gluster shared

Gluster volume is distributed-replicate – replica 2

Shutting down servers one at a time all work except for 1 brick. If we shut
down one specific brick (1 brick per host) – we’re unable to activate the
storage domain. VM’s that were actively running from other bricks continue
to run. Whatever was running form that specific brick fails to run, gets
paused etc.

Error log shows the entry below. I’m not certain what it’s saying is read
only…nothing is read only that I can find.

According to Ovirt/Gluster, if a brick goes down, the VM should be able to be
restarted from another brick without issue. This does not appear to be the
case… If we take other bricks offline, it appears to work as expected.
Something with this specific brick cases everything to break which then
makes any VM’s that were running from the brick unable to start.

Do you have the recommended options for using volume as virt store 
turned on? Is client-side quorum turned on for the volume? Is the brick 
that causes the issue, the first brick in the replica set?

[ovirt-users] after rebooting nodes cannot activate them

Hello!


1 engine- not hosted FC 19 + ovirt 3.5 ;
3 nodes - F20 and ovirt 3.5 patternfly due to high vdsm memory usage. All
theree nodes serves as glusterfs server - 3 replicated bricks.
After putting DC in maintenance -  all VM shutdown, storages in maintenance
(ISO, Data, Export) , stop gluster volume and finally hosts in maintenance
, runned "yum update" on all nodes, reboot them, "Confirm host has been
rebooted" but trying to activate them raise "Gluster command []
failed on server." and hosts goes in non operational.

The oVirt websocket proxy is part of the engine and it's by default installed 
on the engine host when you install the engine; engine-setup asks if you want 
to configure it or not.
Than, if you really need for your network design, you can also install and 
configure the websocket proxy on a different host.
 http://www.ovirt.org/Features/WebSocketProxy_on_a_separate_host
but this is already a special case.

I read in this thread that you are using centos7 (also for the engine host?).
We didn't release oVirt 3.5.0 for el7 but we'll do since 3.5.1 which is 
targeted just after Christmas vacation (you are welcome to help us testing it 
on centos7!) so now you still cannot find ovirt-websocket-proxy rpm for el7 on 
the stable branch.
If you really need to install it right now on el7 you can try from nightly 
snapshot.

Re: [ovirt-users] Used Network resources of host XY [97%] exceeded

2014-12-18 Thread InterNetX - Juergen Gotteswinter

i have seen those messages in setups with 10G networking, when the
network throughput went to ~1gbit those messages appeared. regarding to
rhn knowledgebase this is a false alert, seemed like some versions of
ovirt/rhev got this hardcoded.

Re: [ovirt-users] FQDN for vm creating with hosted-engine

2014-12-18 Thread Nikolai Sednev

FQDN convention should be following your organizational domain conventions, as 
long as FQDNS reachable via DNS, should work just fine. 
Normally from the beginning you don't have to edit manually /etc/hosts at all, 
once your HE-VM getting the same IP from reserved range of DHCP IP addresses 
and DNS has its FQDN in its records, since your hosts during 
hosted-engine-deployment will be given already known FQDN of the HE-VM instead 
of its IP, then hosts will get to HE-VM via DNS. 

Using reserved IP address range advised, as during some time, if you're using 
IP addresses from dynamic pool, you'll eventually will loose connectivity to 
your HE-VM, as it's IP will be updated after lease time expires or renewed. 

For repeated HE installations with same FQDN for the engine desired, to get 
always the same IP address for HE-VM, each time you're deploying it, you will 
have to write down it's MAC address, so when asked during deployment to provide 
MAC address for HE-VM, you'll just write manually the same MAC address (that 
very MAC address, that is already matched in reserved DHCP IP<->MAC pair), this 
will ensure that your HE-VM will receive then the same IP address from DHCP and 
will resolve to FQDN in DNS database records. 



Thanks in advance.

FQDN or fully qualified domain name means that you have to reserve in your DNS 
a name corresponding to IP received by HE VM from DHCP. 
IP address should be reserved for the VM at DHCP. 

I advise not to use manual IP to FQDN at your host, as this will lead to many 
confusions, especially when you'll have more than a single host machine, but 
you always can configure at your /etc/hosts file the FQDN corresponding to IP 
address given to HE VM.

Thanks for the explanation. Now I understand what FQDN is for Ovirt. Is there 
any problem if I do not use the naming convention like aaa.bbb.ccc, but only 
aaa? 
Also I am some confused for the above explanation. Here it said the IP for VM 
is better to be got from DHCP rather than manual IP. If so, do this mean I need 
to change all /etc/hosts file of all virt nodes to update the IP for the FQDN 
for engine VM? 
What is the confusions if I use manual IP rather than DHCP for engine VM? 

Thanks, 
Cong

Re: [ovirt-users] vm has paused due to unknown storage error

2014-12-18 Thread Martijn Grendelman

Hi,

On a new host, I am running into exactly the same scenario.

I have a host with an oVirt-managed GlusterFS volume (single brick on
local disk in distribute mode) on an XFS file system.

I think I have found the root cause, but I doubt I can fix it.

Around the time of the VMs going paused, there seemed to be a glusterfsd
restart:

So I thought I'd check /var/log/messages for potential sources of the
SIGTERM, and I found this:

[ovirt-users] Get involved in oVirt project! Xmas edition

2014-12-18 Thread Sandro Bonazzola

Hi,
have you got some free time in upcoming holidays and do you want to get 
involved in oVirt project?
Here are some bugs you can hopefully fix in less that one day or you can just 
try to reproduce providing info:

Bug 1080823 - [RFE] make override of iptables configurable when using 
hosted-engine
Bug 1065350 - hosted-engine should prompt a question at the user when the host

[ovirt-users] qemu update & Windows activation

2014-12-18 Thread Markus Stockhausen

Hello,

we just build a new cluster with FC20 + virt-preview repos enabled.
Idea behind that is to enable snapshot live merge feature. This
seems to work quite well.

The only culprit is the Windows activation. For some reasons the
VM hardware of the old qemu 1.6/seabios 1.7.3 hypervisors is
different to the new qemu 2.1/seabios 1.7.5. So the OS is no longer
activated.

We already activated the VMs twice. During first install on VMware
and then afterwards after the migration to OVirt. I have no problem
to reactivate them a third time. I have more fears that I must
reactivate them with each new hypervisor generation. That can
be quite a lot of phone calls.

An interesting article from the Proxmox guys can be read here:
http://forum.proxmox.com/archive/index.php/t-19743.html
Conclusion of the discussion: After you go from qemu 1.7 to 2.1
you can force the old hardware layout using -M pc-i440fx-1.7

Looking at the qemu command line in OVirt I can see our VMs
are fired up with pc-1.0,accel=kvm,usb=off - regardless of an
old (FC20) or a new hypervisor (FC20+virt-preview). So I would
guess that everything should work without a new reactivation.

Any ideas?

Markus

[ovirt-users] Problem with installing second host for hosted_engine (3.5)

2014-12-18 Thread Otto Strassen

Hi

I have set up oVirt 3.5 in a hosted engine configuration. Host running CentOS 
7, guest CentOS 6.6.

Now I'm trying to set up an additional host, also running CentOS 7. I'm doing 
this by running 'hosted-engine --deploy' on the second host, giving the NFS 
address of the hosted engine share and following the instructions (Do you want 
to copy over answers? etc.) It works up to the point where it asks for the 
admin@internal password.

[ovirt-users] IPv6 Functionality for WebSocket Proxy

I just realized this morning that my noVNC connections were not working for
IPv6 only on cloudspin.me

For those who want to deploy dual stack functionality for
ovirt-websocket-proxy here is a very simple and elegant fix. 

 

NGINX is a useful tool :)

 

You will need nginx to proxy the connection between your IPv6 customers, and
the IPv4 listening only websocket proxy(however that can be changed in
/usr/share/ovirt-engine/services/ovirt-websocket-proxy/ovirt-websocket-proxy
.conf but you can't have your cake and eat it too. one or the other ipv4 or
ipv6)

Anyways, here is the fix

 

Install nginx on your websocket proxy server - Why Nginx, because I like it
better than apache. The default config for Ovirt could be setup to do this
with the web server that is already running :) just sayin

For my configuration I am running the websocket proxy on a different host,
but I imagine you could use this config in a full deployment and use
websocket proxy on the engine host

 

server {

server_name web.cloudspin.me; # this is the hostname that you told
the engine that the websocket proxy would be listening on

#listen 6100; #Commented because I am using this for
ipv6 only, but you could use nginx to proxy both and only open one port in
the firewall

listen [::]:6100 ssl; #NOTE this needs to listen on the same
port you told the engine the websocket proxy would be listening on   

ssl_certificate   /physical/path/to/ssl/cert; #I used the
same cert that my websocket proxy is using

ssl_certificate_key   /physical/path/to/ssl/key;

 

ssl on;

ssl_session_cache  builtin:1000  shared:SSL:10m;

ssl_protocols  TLSv1 TLSv1.1 TLSv1.2;

ssl_ciphers
HIGH:!aNULL:!eNULL:!EXPORT:!CAMELLIA:!DES:!MD5:!PSK:!RC4;

ssl_prefer_server_ciphers on;

 

access_log /var/log/nginx/websocket.cloudspin.me-access.log;

error_log /var/log/nginx/websocket.cloudspin.me-error.log;

 

location / {

proxy_pass https://ip_address_of_websocket_proxy:6100;

  proxy_http_version 1.1;

  proxy_set_header Upgrade $http_upgrade;

  proxy_set_header Connection "upgrade";

   

}

}

 

 

Too easy to fix the many problems I have had getting websocket proxy to
work. If you have a commerical cert and key, this would be a great place to
put it, so your users don't have to bother with trusting your CA, it will
just work 

 

Cheers and I hope this helps

 

If anyone needs any help getting this to work give me a shout

Re: [ovirt-users] IPv6 Functionality for WebSocket Proxy

I would also like to note that if nginx and websocket proxy are on the same
machine you cannot have both nginx and websocket proxy listening on 6100. it
would be best to change the websocket proxy listening port and then proxy
both ipv4 and 6 with nginx :)

The thing is that the mount options is correct and the file exists. It's a

It's  a know issue [1] due to a not well supported NFS configuration; it's 
still unsolved.
Can please ensure to export like:
/storage*(rw,sync,no_subtree_check,all_squash,anonuid=36,anongid=36)
to avoid it as documented here [2].

Re: [ovirt-users] Problem with installing second host for hosted_engine (3.5)

2014-12-18 Thread Otto Strassen

Thank you for you quick reply. To understand correctly, I don't need to use 
/storage as path, I can keep the path and just need to add no_subtree_check? Or 
is the problem related to the whole configuration. (i.e. I need to do a fresh 
setup?)

Yes, the bug is related to server NFS options, not to the export name.
Using (rw,sync,no_subtree_check,all_squash,anonuid=36,anongid=36)
should be enough to be able to deploy the second host. 

> Or is the problem related to the whole configuration. (i.e. I need to do a

As far as I know fixing the export options and reloading it should be enough to 
fix the issue on the second host.
As far as I know, no need to redeploy also the first one.

Please let us know if it work cause the issue is still open.

Thanks

The oVirt websocket proxy is part of the engine and it's by default installed 
on the engine host when you install the engine; engine-setup asks if you want 
to configure it or not.
Than, if you really need for your network design, you can also install and 
configure the websocket proxy on a different host.
 http://www.ovirt.org/Features/WebSocketProxy_on_a_separate_host
but this is already a special case.

I read in this thread that you are using centos7 (also for the engine host?).
We didn't release oVirt 3.5.0 for el7 but we'll do since 3.5.1 which is 
targeted just after Christmas vacation (you are welcome to help us testing it 
on centos7!) so now you still cannot find ovirt-websocket-proxy rpm for el7 on 
the stable branch.
If you really need to install it right now on el7 you can try from nightly 
snapshot.

The oVirt websocket proxy is part of the engine and it's by default installed 
on the engine host when you install the engine; engine-setup asks if you want 
to configure it or not.
Than, if you really need for your network design, you can also install and 
configure the websocket proxy on a different host.
 http://www.ovirt.org/Features/WebSocketProxy_on_a_separate_host
but this is already a special case.

I read in this thread that you are using centos7 (also for the engine host?).
We didn't release oVirt 3.5.0 for el7 but we'll do since 3.5.1 which is 
targeted just after Christmas vacation (you are welcome to help us testing it 
on centos7!) so now you still cannot find ovirt-websocket-proxy rpm for el7 on 
the stable branch.
If you really need to install it right now on el7 you can try from nightly 
snapshot.

Re: [ovirt-users] EXTNET Hook and Libvirtd "Default" Network Setup

2014-12-18 Thread Andrew Wagner


Lior,

The main purpose of this is for testing. Medium-term, my plan is to spin 
up another VLAN and routable private subnet with DHCP to trunk our 
virtualization hosts onto. That requires more people to get involved to 
get the testing environment in place. I suppose I can spin up a DHCP 
server and private network outside of libvirt on the machine itself and 
add to oVirt.

Hi Andrew,

All,

I'm testing out oVirt for one of our projects that wants to try an
all-in-one setup before going to a larger deployment. For their testing,
they want to use the default NAT'd network from libvirtd on the host.

I've install oVirt, installed the extnet hook, enabled IP forwarding in
sysctl.conf and loaded the setting, and created a vm that attaches to
the libvirtd "default" network and gets an IP. The VM can ssh to the
virbr0 IP address, in this case 192.168.122.1, to access the host.
However, the VM cannot reach any IP address off of the NAT'd subnet. I
haven't changed any of the default iptables rules that oVirt and
libvirtd create. Looking at ip route and the iptables rules, I feel that
traffic should be getting directed appropriately.

Could you elaborate why there's need to meddle with the networking at
the level of libvirt and to use the extnet hook?

If all you need is an IP address and NAT, I would think a default oVirt
setup would do as long as you have a DHCP server and add proper iptables
rules to the host.

Even if you do in fact need the specific libvirt network and to use the
hook, maybe it's worth trying without them first - just to make sure
your iptables rules are alright (they would be my prime suspect).


Does anyone have any thoughts as to what the issue may be? For some
reason, the ovirtmgmt bridge doesn't seem to be receiving or allowing
traffic from virbr0 to pass across it. I can provide more information if
that would be helpful!

[ovirt-users] architecture of ovirt in case of using hosted-engine

I understand ovirt have ovirt engine and ovirt nodes. For ovirt engine, it can 
be hosted on the top of ovirt nodes as one VM.

I am using hosted-engine to try to do this.
When I try to deploy the second ovirt node.
I did
Hosted-engine -deploy

And is asks me when I want to create a VM where you have to install oVirt 
Engine afterwards. I am some confused whether this means another new engine VM 
will be created into the second ovirt nodes?

Also I met a problem for the second ovirt node deployment. In the event, it 
saids "Failed to connect to Host hosted_engine_2 to Storage domain data".
As for I met the same problem for /engine, and I just used nfs4 and it works. 
Is there some way I can redeploy it? Do I need do hosted-engine -destroy-VM?

Thanks,
Cong

[ovirt-users] Can not connect to Storage domain data

Hi

I successfully deployed the first ovirt host with hosted-engine -deploy. Engine 
VM works well.
While, when I try to create the second host with the same way as the guide of
http://community.redhat.com/blog/2014/11/up-and-running-with-ovirt-3-5-part-two/

I am not using GlusterFS, and just use one external storage(nfs) in my 
environment.

The issue I have is in the engine administration menu, it says "can not connect 
to storage domain data"
In the second host, I checked with nfs-check.py for both storage and data 
domain. It shows the status is ok.
http://www.ovirt.org/Troubleshooting_NFS_Storage_Issues


During deployment of the second host, how the data domain is trying to be 
mounted?

Thanks,

Re: [ovirt-users] Can not connect to Storage domain data

I think the problems for my issue are related with the NFS version.

Also from /proc/mounts, it shows the nfs version is nfs4. But for my first 
host, it is nfs3.

Do somebody have the similar issue about thi?

Thank in advance,

Subject: Can not connect to Storage domain data

Hi

I successfully deployed the first ovirt host with hosted-engine -deploy. Engine 
VM works well.
While, when I try to create the second host with the same way as the guide of
http://community.redhat.com/blog/2014/11/up-and-running-with-ovirt-3-5-part-two/

I am not using GlusterFS, and just use one external storage(nfs) in my 
environment.

The issue I have is in the engine administration menu, it says "can not connect 
to storage domain data"
In the second host, I checked with nfs-check.py for both storage and data 
domain. It shows the status is ok.
http://www.ovirt.org/Troubleshooting_NFS_Storage_Issues


During deployment of the second host, how the data domain is trying to be 
mounted?

Thanks,

Re: [ovirt-users] Free Ovirt Powered Cloud

Its in the works, but I personally have no problems leaving it oob. The
Ovirt developers worked very hard to create what they have, and I'm not
afraid to left their flag fly. 

I just don't have the time right now to create all the graphics and what
not. I take my rhcsa tomorrow and I have been focused on that this month :) 

My next step now that I see there is interest, I  have plans to contact
datacenters all around and see if they will donate a server or two for the
cause. I know sounds ambious, but what can they tell me... no

Thanks for the kudos

Very nice! Not sure what your plans are, but wanted to point out that you
can brand oVirt for your company. It might add a nice touch :)

Re: [ovirt-users] qemu update & Windows activation

2014-12-18 Thread Itamar Heim


On 12/18/2014 05:13 PM, Markus Stockhausen wrote:

Hello,

we just build a new cluster with FC20 + virt-preview repos enabled.
Idea behind that is to enable snapshot live merge feature. This
seems to work quite well.

The only culprit is the Windows activation. For some reasons the
VM hardware of the old qemu 1.6/seabios 1.7.3 hypervisors is
different to the new qemu 2.1/seabios 1.7.5. So the OS is no longer
activated.

We already activated the VMs twice. During first install on VMware
and then afterwards after the migration to OVirt. I have no problem
to reactivate them a third time. I have more fears that I must
reactivate them with each new hypervisor generation. That can
be quite a lot of phone calls.

An interesting article from the Proxmox guys can be read here:
http://forum.proxmox.com/archive/index.php/t-19743.html
Conclusion of the discussion: After you go from qemu 1.7 to 2.1
you can force the old hardware layout using -M pc-i440fx-1.7

Looking at the qemu command line in OVirt I can see our VMs
are fired up with pc-1.0,accel=kvm,usb=off - regardless of an
old (FC20) or a new hypervisor (FC20+virt-preview). So I would
guess that everything should work without a new reactivation.

Any ideas?

Markus

for .el6/.el7 we use the stable -m machines (-m rhel6.5.0, -m

fedora uses "pc" indeed. you can change it via config, but I don't know 
fedora is keeping these stable for the other definitions / how to map

Re: [ovirt-users] Can not connect to Storage domain data

I found the workaround for this.

For some reason my Storage domain of data can not be mounted. I just mount it 
manually, like

mount -t nfs nfs2-3:/data /rhev/data-center/mnt/nfs2-3:_data

Actually, the folder of "/rhev/data-center/mnt/nfs2-3:_data" has been created. 
I think this may be some bug as for in my environment, I will reproduce it 
always if I try to deploy the host from second time.

Thanks,
Cong
