[Users] Networking questions (LONG)
Hello, I am evaluating oVirt as a replacement/alternative to VMware deployments we typically do. I have installed and all-in-one setup on a test box (which itself used to be an ESXi server), but it only has one NIC. I trying to duplicate our typical configuration we do in VMware, which is this: 1.) we create several port groups on the vSwitch, each assigned a VLAN ID, such as: - VLAN001 (VLAN ID: 1) - VLAN002 (VLAN ID: 2) - VLAN009 (VLAN ID: 9) - VLAN010 (VLAN ID: 10) - VLAN200 (VLAN ID: 200) - TRUNK (VLAN ID: 4095 - in VMware-world, VLAN ID 4095 is all VLANS and basically just passes the VLANs through to whatever is attached to the port group for the VM to handle) 2.) We assign VMs to port groups appropriate for the VLAN they are part of. 3.) The only VM that has a NIC assigned to the TRUNK port group is the firewall (which is Linux), and we create VLAN interfaces on it (i.e., eth1.1, eth1.2, eth1.10, eth1.200). The firewall VM acts as the router between the various VLANs. To replicate the above in oVirt, I created logical networks for each VLAN, and assigned the appropriate VLAN ID. It seems oVirt/KVM does not have an equivalent for VMware's VLAN ID of 4095, so after some searching around, so for the TRUNK network, I left it with no VLAN assigned. Because i cannot add VLAN and non-VLAN networks to the same physical NIC, after some searching around, it looks like I may have to utilise two NICS: one for the VLAN networks and one for the TRUNK network. Because, at this point, I am not yet concerned with making the test VMs I will be setting up be accessible from outside the virtual lab environment (i.e., everything will communicate within my oVirt server/network for now), I am trying to make use of dummy interfaces, but I am not sure the best way to make use of this. I am able to create the dummy* interfaces and have them show up in oVirt, but I am not sure of how they should be setup. Here is what I am *thinking* should be done, but want to make sure it is correct before getting too deep: - I will use the physical NIC for management, therefore the ovirtmgmt bridge with eth0 assigned to it will remain as-is - Create two dummy interfaces: dummy0 and dummy1 - Create a new bridge, ovirtvm and assign dummy0 and dummy1 to it - Attach the VLAN-enabled networks to dummy0 - Attach the TRUNK network to dummy1 Would the above be the way to go about this? The one thing I am not sure of is whether or not having no VLAN assigned (on the TRUNK network) accomplishes the same this as the VLAN ID 4095 in VMware: will oVirt/KVM just pass the traffic through for the VM attached to it to deal with? Thanks for reading this far, and I appreciate any help you might be able to lend in the above. -Alan ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users
Re: [Users] Experience with low cost NFS-Storage as VM-Storage?
another point is, that a correct configured multipathing is way more solid when it comes to a single path outage. at the software side, i have seen countless nfs servers which where unresponsive because of lockd issues for example, and only a reboot fixed this since its kernel based. another contra for me is, that its rather complicated and a 50/50 chance that a nfs failover in a nfs ha setup works without any clients dying. dont get me wrong, nfs is great for small setups. its easy to setup, easy to scale, i use it very widespread for content sharing and homedirs. but i am healed regarding vm images on nfs.

The minimal differences in performance usually only show up if you drive the storage to its limits. I guess you could help Sven better if you had some hard facts why to favour ISCSI. Best regards. Markus Only technical difference I can think of is the iSCSI-level load-balancing. With NFS you set up the network with LACP and let that load-balance for you (and you should probably do that with iSCSI as well but you don´t strictly have to). I think it has to do with a chance of trying to go beyond the capacity of 1 network interface at the same time, from one Host (higher bandwidth) that makes people try iSCSI instead of plain NFS. I have tried that but was never able to achieve that effect, so in our situation, there´s no difference. In comparing them both in benchmarks, there was no performance difference at all, at least for our storage systems that are based on FreeBSD. /K -- Sent from the Delta quadrant using Borg technology! ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users
[Users] Bug? in tweak vm instance via REST/JSON 3.3.2
Hi,
we got a problem with starting a vm after changing some of its
parameters via REST (JSON)
this is the command to create the vm (this works):
POST request on https://virt-mgmt-01.internal/api/vms/
{name:vr2,cluster:{id:2ad11b5e-9e74-499a-b317-5a9a3027cfca},template:{id:374a12df-5ffc-4feb-a2bf-c912f059675f}}
Then we tweak memory and cpu:
PUT request on
https://virt-mgmt-01.internal/api/vms/42dba82f-e7ea-40ff-a76e-70056912b47f
{memory:2048,cpu:{topology:{sockets:1,cores:1}}}
and then we start it:
POST request on
https://virt-mgmt-01.internal/api/vms/42dba82f-e7ea-40ff-a76e-70056912b47f/start

the error we get:
Operation Failed,detail:[Cannot run VM. There is no host that
satisfies current scheduling constraints. See bellow for details:]
when we start the vm without altering memory and cpu it starts just
fine.
Is this not supported via JSON, or is this a bug?

[Users] Network unsynchronised
Hi All. I have a brand new, fresh all-in-one installation that I am using to evaluate oVirt. I have removed the VM network role from the ovirtmgmt bridge, as I want to use it for management only, and no VMs (I plan on using other networks I am creating with VLAN IDs for handling the VM network). I can remove the role alright, but when I go in to Setup Host Network, the ovirtmgmt network is showing as being unsynchronised. When I click on the pencil icon on the network to edit it, I put a check in Sync Network and clik OK but it never seems to sync. Any idea why it will not?

[Users] Migration from NFS backed VM to iSCSI LUN without exporting them on the Ovirt Export Share
Hello folks, since the nfs discussion remembered me that i got some vm left to migrate... here some kind of special question. i am open for non-bestpractice hacky solutions, too Situation is: - 2 Ovirt Cluster - Same DC - one NFS backed, one iSCSI backed - NFS Share and iSCSI Share are exported from the same phys. Machine - Bot DC use the same filer, just different Luns / Protocolls so, i thought about something simple like just move vm folder from a to b and do a little bit database voodoo? anyone did something like this yet? or is storage live migration already working for this? the docs didnt tell me very much about this.

One other question to add: If I do indeed ned to create a new bridge (ovirtvm in my example), I do not want to assign any IPs to it, nor any of the logical networks I create. When I did try this in my fooling around, oVirt would not let me save the changes, giving me an error about network parameters not correct (I have the host shut down a the moment, so I can get the exact message, but if necessary, I can get it for you when I get in to our shop in the morning) Thanks! :-) -Alan ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users

Re: [Users] Specifying values for cert, key, and CA for ovirt-shell

No experience there but I can make some suggestions.

[Users] VirtIO disk latency
Hello, coming from the low cost NFS storage thread I will open a new one about a topic that might be interesting for others too. We see a quite a heavy latency penalty using KVM VirtIO disks in comparison to ESX. Doing one I/O onto disk inside a VM usually adds 370us of overhead in the virtualisation layer. This has been tested with VirtIO-SCSI and windows guest (2K3). More here (still now answer yet): http://lists.nongnu.org/archive/html/qemu-discuss/2013-12/msg00028.html A comparison for small sequential 1K I/Os on a NFS datastore in our setup gives: - access NFS inside the hypervisor - 12.000 I/Os per second - or 83us latency - access DISK inside ESX VM that resides on NFS - 8000 I/Os per second - or 125us latency - access DISK inside OVirt VM that resides on NFS - 2200 I/Os per second - or 450us latency Even the official document at http://www.linux-kvm.org/page/Virtio/Block/Latency suggest that the several mechanisms (iothread/vcpu) at least have a overhead of more than 200us Has anyone experienced something simlar. If these latency are normal it would make no sense to think about SSDs inside a central storage (be it ISCSI or NFS or whatever).

What is your exact testing method? ( commands, file sizes, sofware versions, mount options etc.) Thanks for taking time to help. I have used several tools to measure latencies but it always boils down to the same numbers. The software components and their releases should not matter to get a first overview. The important thing is to ensure that a read request of a test inside the VM is really passing the QEMU layer. The simplest test I can think of (at least in our case) is to start a Windows VM and attach a very small NFS disk with 1GB to it. Start it, install HDTune Trial and run the random access test to the small disk. Other ways could be to run some kind of direct IO based read test inside the VM. During each test I can see the packets running between the NFS server and the hypervisor so I know that each request is not cached inside the VM or QEMU. After one or two runs the filecache in the RAM of our NFS server has all the hot data and latency decreases down to the microseconds area. With that we can derive the penalty of the virtualization layer. Whatever I try to optimize I only reach 1/4th of the I/Os of ESX for very small packets (512 bytes or 1K). And that inside the same (migrated) VM on the same NFS topology with the same test programs. The baseline numbers for the hypervisor are an average of running direct io based test tools onto files residing on the same NFS. Markus P.S. I'm not complaining about that performance. Driving an IPoIB environment you get used to waste bandwidth and latency. But it is always good to know where it comes from.

That's what I tried first. I get: error: server CA certificate file must be specified for SSL secured connection. And if I don't specify https I get: error: No response returned from server. If you're using HTTP protocol against a SSL secured server, then try using HTTPS instead. OK. Here is what I did: On ovirt-engine: wget https://engine_fqdn/ca.crt --no-check-certificate and used the following .ovirtshellrc [cli] autoconnect = True autopage = True [ovirt-shell] username = admin@internal timeout = -1 extended_prompt = False url = https://engine_fqdn/api insecure = False filter = False session_timeout = -1 ca_file = /root/ca.crt dont_validate_cert_chain = False key_file = None password = ** cert_file = None Something must be different about our setups. This is where I started. In both cases, either insecure = True or when I specify the ca_file only, I get: error: [401] - Unauthorized, HTTP Status 401 The one difference is that you are using ca_file = /root/ca.crt whereas I am using ca_file = ca.pem. I can't seem to find any .crt files in the /etc/pki/ovirt-engine area (or, for that matter, in the /etc/pki/vdsm area on the node). You have missed the step where I downloaded ca.crt with wget :-) The key_file and cert_file parameters are only needed when your web server has been manually configured to require client SSL certificates, and this isn't the default configuration, so leave them with None as the value. The only SSL parameter that you need to change is ca_file, and it should contain the absolute path name of the file containing the certificate of the authority that signed the certificate of the web server. If you didn't change the SSL configuration of the web server then this file is in /etc/pki/ovirt-engine/ca.pem. So, to summarize, the parameters that you need to change are the following: url = https://your_fully_qualified_host_name/api username = admin@internal password = the_password_for_the_above_user ca_file = /etc/pki/ovirt-engine/ca.pem -- Dirección Comercial: C/Jose Bardasano Baos, 9, Edif.

[Users] VSDM´s logrotate makes Hosts fill up var eventually
Hi!
I just noticed my Hypervisor nodes starting to complain about disks
almost being full. I started investigation and noticed that:
# du -h /var/log/libvirtd.log
100G/var/log/libvirtd.log
And many Hosts system partition had indeed become full:S
Why weren´t the file rotated? Well:
# ls -lah /var/log/libvirtd.log.* | wc -l
100
And the rotate policy says:
/etc/logrotate.d/libvirtd
## beginning of configuration section by vdsm
/var/log/libvirt/libvirtd.log {
rotate 100
missingok
copytruncate
size 15M
compress
compresscmd /usr/bin/xz
uncompresscmd /usr/bin/unxz
compressext .xz
}
Now, I just handled it by changing 100 to 1000 but I think that a
better default needs to be placed in general, don´t you?

Re: [Users] VSDM´s logrotate makes Hosts fill up var eventually
Hi,
I also guess this gets so large because of the loglevels in
/etc/vdsm/logger.conf
this seems to be the default:
[logger_root]
level=DEBUG
handlers=syslog,logfile
propagate=0
[logger_vds]
level=DEBUG
handlers=syslog,logfile
qualname=vds
propagate=0
[logger_Storage]
level=DEBUG
handlers=logfile
qualname=Storage
propagate=0
[logger_metadata]
level=WARNING
handlers=metadata
qualname=irs.metadata
propagate=0
[handler_syslog]
level=WARNING
class=handlers.SysLogHandler
formatter=sysform
args=('/dev/log', handlers.SysLogHandler.LOG_USER)
[handler_logfile]
class=logging.handlers.WatchedFileHandler
args=('/var/log/vdsm/vdsm.log',)
filters=storage.misc.TracebackRepeatFilter
level=DEBUG
formatter=long
[handler_metadata]
class=logging.handlers.WatchedFileHandler
args=('/var/log/vdsm/metadata.log',)
level=WARNING
formatter=long
which is debug level for most loggers.
Question to the devs:
Is this really needed as a default in a production
environment?
my vdsm is a little bit older btw:
vdsm-4.12.1-4.el6.x86_64
vdsm-cli-4.12.1-4.el6.noarch
vdsm-python-4.12.1-4.el6.x86_64
vdsm-python-cpopen-4.12.1-4.el6.x86_64
vdsm-xmlrpc-4.12.1-4.el6.noarch
did this change in vdsm 4.13. ?

[Users] Network not sync and problems reconfiguring
Hi, Out of the blue some of the hosts got some LNs out of sync (not the same in all of them). If I try to resync the LN, it does not show a resync option, so I took one host and detached the lns and reconfigured them. After that, ovirtmgmt is not created correctly, it does not create the vlan interface on top of the bond and also, it's adding the bond to the bridge instead of the vlan interface. I got it partially running but it's still non operational as the engine complains the host can't mount the gluster domain (it can reach the network of the other brick): [root@ovirt4 network-scripts]# gluster volume status Status of volume: glusterfs Gluster processPortOnlinePid -- Brick 192.168.128.82:/glusterfs49154Y13288 Brick 192.168.128.83:/glusterfs49154Y5961 NFS Server on localhost2049Y4557 Self-heal Daemon on localhostN/AY4558 NFS Server on 192.168.128.822049Y15815 Self-heal Daemon on 192.168.128.82N/AY15819 I'm not synchronizing any other host just in case this happens to the other host too.

Re: [Users] Network not sync and problems reconfiguring
Ok, so far I found that ovirtmgmt lost it's vlan tag configuration. If I try to put it back, I get and error because the LN is attached to hosts. I can't detach it as the engine won't let me. If I try to delete the host to re add it, it complanits that it's a brick of the volume this is frustrating... Is there a way to fix this without destroing the hole DC?

Hi!
I just noticed my Hypervisor nodes starting to complain about disks

And many Hosts system partition had indeed become full:S
Why weren´t the file rotated? Well:
# ls -lah /var/log/libvirtd.log.* | wc -l
100
And the rotate policy says:

I do not understand this issue, Karli. After 100 log files have been
created, the oldest one should have been removed and replaced by the
newest one. logrotate is expected to be called every 15 minutes, so it
should not have stayed above 15M for so long. Do you see any error when
running `/usr/sbin/logrotate /etc/logrotate.d/libvirtd` as root?
What the funk, it doesn´t do anything, complains nothing like it´s done what
it´s supposed to, and no errors in /var/log/messages either...
better default needs to be placed in general, don´t you?

The question of how much logging we should keep is a tough one. I, as a
developer, would like to have as much as possible. For long-running busy
systems, it has happened to me that the core bug was spotted in
vdsm.log.67 or so.
However, I understand that verbosity has its price. To understand
whether we are stable enough to change the defaults, I need volunteers:
people who are willing to change their log level to INFO or WARNING, and
see if they miss useful information from their logs.
When you make you log level higher, you can lower the number of kept
log files, as they would not be filled as quick.
Would you, users@, help me with hard data?
Well, I understand that having more data of course helps when there´s an issue,
however having lots of data isn´t helping in this particular case;P
Seriously though, it´s not bothering me having lots of logs. I don´t mind the
DEBUG mode, and as long as rotate _does what it´s supposed to_ (but that´s
besides the point) it´s not taking up that much space to argue about either so
for me it´s cool (normally).

Re: [Users] [Gluster-users] Creation of preallocated disk with Gluster replication
Hello Darell, Le 2014-01-08 18:47, Darrell Budic a écrit : Grégoire- I think this is expected behavior. Well, at least the high glusterfsd CPU use during disk creation, anyway. I tried creating a 10 G disk on my test environment and observed similar high CPU usage by glusterfsd. Did the creation on the i5 system, it showed 95%-105% cpu for glusterfsd during creation, with the core2 system running ~35-65% glusterfsd utilization during the creation. Minor disk wait was observed on both systems, 10% peak and generally 5%. I imagine my ZFS cached backends helped a lot here. Took about 3 minutes, roughly what I’d expect for the i5’s disk system. Does that mean that glusterfs + ovirt absolutely need to be separated so that changes on glusterfs have no negative impact on VM in production ? Here I got the problem with the creation of a preallocated disk but if tomorrow I want to change the way I replicate glusterfs bricks, I guess I'll have the same issue. Network usage was about 45% of the 1G link. No errors or messages logged to /var/log/messages. If checked with iftop to be more accurate, and I can see it uses more than 95% with my setup. Depending on what your test setup looks like, I’d check my network for packet loss or errors first. I did, I have 0 network error and 0% packet loss (for this latter, I just used ping with the ovirtmgmt interface, which showed 0% packet lost while my server was considered as down by Ovirt). Then look at my storage setup and test pure throughput on the disks to see what you’ve got, maybe see what else is running. Did you use an NFS cluster or a PosixFS cluster for this? I use PosixFS cluster for this. My detailed setup is : Intel(R) Xeon(R) CPU E5-2420 0 @ 1.90GHz (*12), 65GB Ram Disk (both boot and storage) : Perc H710 2To, hardware RAID 1 2 1G ethernet in bonding (failover) Intel(R) Xeon(R) CPU E5-2609 0 @ 2.40GHz (*8), 64GB Ram Disk (boot + storage) : Perc H310 1G ethernet I'm pretty sure there isn't any problem with the switch between them. To conclude : 1) About the network issue, I think it could be possible to use iptables with QoS rules on specific ports to limit GlusterFS throughput. 2) However, the CPU issue seems to be more difficult to avoid. I guess I just have to review my architecture... Thank you, Regards, Grégoire Leroy ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users

I think this feeling is in part because it takes a bit of work me, an experienced power admin but not developer, to dig stuff out of the logs myself, and most of it is not useful to me.

Re: [Users] Networking questions (LONG)
Hello Alan, On 09/01/14 10:07, Alan Murrell wrote: Hello, I am evaluating oVirt as a replacement/alternative to VMware deployments we typically do. I have installed and all-in-one setup on a test box (which itself used to be an ESXi server), but it only has one NIC. I trying to duplicate our typical configuration we do in VMware, which is this: 1.) we create several port groups on the vSwitch, each assigned a VLAN ID, such as: - VLAN001 (VLAN ID: 1) - VLAN002 (VLAN ID: 2) - VLAN009 (VLAN ID: 9) - VLAN010 (VLAN ID: 10) - VLAN200 (VLAN ID: 200) - TRUNK (VLAN ID: 4095 - in VMware-world, VLAN ID 4095 is all VLANS and basically just passes the VLANs through to whatever is attached to the port group for the VM to handle) 2.) We assign VMs to port groups appropriate for the VLAN they are part of. 3.) The only VM that has a NIC assigned to the TRUNK port group is the firewall (which is Linux), and we create VLAN interfaces on it (i.e., eth1.1, eth1.2, eth1.10, eth1.200). The firewall VM acts as the router between the various VLANs. To replicate the above in oVirt, I created logical networks for each VLAN, and assigned the appropriate VLAN ID. It seems oVirt/KVM does not have an equivalent for VMware's VLAN ID of 4095, so after some searching around, so for the TRUNK network, I left it with no VLAN assigned. Because i cannot add VLAN and non-VLAN networks to the same physical NIC, after some searching around, it looks like I may have to utilise two NICS: one for the VLAN networks and one for the TRUNK network. That is true. One non-VLAN network can in fact sit on the same NIC with VLAN networks, but it has to be non-VM. However, I'm not sure that you in fact need a TRUNK VM network in oVirt. If you want your firewall VM to get all traffic from the VLANs, you could create a vNIC for each network, to which you'll attach a profile (oVirt's equivalent of port group if I'm not mistaken) of the corresponding network. The host can remain with just the VLAN networks attached to its NICs, without a designated TRUNK. This way the firewall VM will get something like eth1 for VLAN 1, eth2 for VLAN 200 and so forth, which might be close enough to what you described on your previous setup (oVirt currently doesn't allow creating VLANs inside VMs). And if I correctly understood your needs it will save you the trouble you described below (well, you would need the one dummy interface). Because, at this point, I am not yet concerned with making the test VMs I will be setting up be accessible from outside the virtual lab environment (i.e., everything will communicate within my oVirt server/network for now), I am trying to make use of dummy interfaces, but I am not sure the best way to make use of this. I am able to create the dummy* interfaces and have them show up in oVirt, but I am not sure of how they should be setup. Here is what I am *thinking* should be done, but want to make sure it is correct before getting too deep: - I will use the physical NIC for management, therefore the ovirtmgmt bridge with eth0 assigned to it will remain as-is - Create two dummy interfaces: dummy0 and dummy1 - Create a new bridge, ovirtvm and assign dummy0 and dummy1 to it This is something that currently can't be done from within the oVirt engine, but if my above suggestion works for you then it won't be needed. - Attach the VLAN-enabled networks to dummy0 - Attach the TRUNK network to dummy1 Would the above be the way to go about this? The one thing I am not sure of is whether or not having no VLAN assigned (on the TRUNK network) accomplishes the same this as the VLAN ID 4095 in VMware: will oVirt/KVM just pass the traffic through for the VM attached to it to deal with? Thanks for reading this far, and I appreciate any help you might be able to lend in the above. -Alan ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users

[Users] Hypervisor info
Dear all, Because of our puppet integration at work, it would like to know if there is a way in ovirt to know, from WITHIN a virtual machine, the hypervisor on wich the vm is running? Kind regards, Koen ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users
Re: [Users] Ovirt Engine single point of failure
OK, so just so I understand this, in the described scenario of three servers: one management server/engine and two nodes, let's say the management server suffers catastrophic hard disk failure where no data can be recovered from it, nor were any backups made. Is it possible to perform a new installation of ovirt-engine, add the two existing nodes, and everything just works? Or would you at least need to do some reconfiguring (e.g., re-add the logical networks etc.) Basically, even though the nodes were part of the now-dead ovirt-engine, there would be no problem in getting them added in to the newly-installed ovirt-engine? -Alan ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users
Re: [Users] Ovirt Engine single point of failure
Alan, IMHO this is not the scenario described in the original question - or maybe I did not understand well the original question? I assume the original question is about a scenario where engine restarts, and not about a catastrophic failure as you describe here. - Original Message - From: Alan Murrell li...@murrell.ca To: users@ovirt.org Sent: Friday, January 10, 2014 9:01:14 AM Subject: Re: [Users] Ovirt Engine single point of failure OK, so just so I understand this, in the described scenario of three servers: one management server/engine and two nodes, let's say the management server suffers catastrophic hard disk failure where no data can be recovered from it, nor were any backups made.

Re: [Users] virtualized engine / port to self-hosted engine
Awesome! Is it worth while trying it now, or should I wait for 3.4 beta?

I currently need to move an AIO configuration from AMD hardware to Intel I7 hardware. The engine-backup WIKI discusses backups, but not restores. I am a bit concerned about using engine-backup to restore an AIO configuration to a different system as another WIKI page with step-by-step instructions to do what engine-backup does for you, mentions you have to do some extra steps if you are changing hostnames as the hostname of the ovirt-engine is embedded in the database. Changing the hostname is specifically not in the scope of engine-backup. Note that you do not need to have the hostname equal to the fqdn input during engine-setup - this last one just needs to be dns-resolvable and point to the machine intended. Also, there is another utility to do that, called ovirt-engine-rename - see this for details and implications: http://www.ovirt.org/Changing_Engine_Hostname There really needs to be some work done in Ovirt on making it easier to import existing disk images and just generally moving things around without having to bounce off an NFS server.

Best regards, -- Didi Sorry for going slightly off topic, but how is everyone's hosted engine deployment going? Are you restricted to NFS? Andrew, in general I get positive feedbacks from RHEL users. For Fedora and other distros, this should be in a better situation in the following 1-2 weeks when we'll have 3.4 beta available. I'd love to get your feedback on it. I missed your NFS question, sorry; Yes. Currently we have NFS limitation and we will do our best to see if SAN can be added. Note that time is not on our side for 3.4. worth mentioning you can use hosted engine on an iscsi/FC cluster - just the hosted engine VM needs to be on NFS I tried the migration procedure last month and it worked.. but had quite a lot of issues so I ended up reverting back. I didn't open any bugs in the assumption it was in super alpha stage. Next time please open bugs... That's the best way to improve the project, regardless of the version state. If unsure, you can always try irc / this list first to see if this is a known issue and if there are workarounds. ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users
