[ovirt-users] Re: Migration not working

[Juan Pablo Lorier]

Hi,

It seems to be fixed now. I updated all the nodes to the last version as 
well as hosted engine. I'll see to look at VDSM logs if it happens again.

Usually issues there can be debugged , when you check the ovirt-ha-broker and 
ovirt-ha-agent logs  (in /var/log on the affected Host).

Sometimes the ova file is compressed/assembled in some way that might

[ovirt-users] Re: OVA import fails always

[Juan Pablo Lorier]

This is not a disk upload, which works fine, this is an import. It loads 
locally from one hypervisor, and the same problem happens on the other 
nodes. I can load the ova, select the vm to import and see all the 
params, then in the import process, it fails.

[ovirt-users] Disk move succeed but didn't move content

[Juan Pablo Lorier]

Hi,

I've a fresh new install of ovirt 4.3 and tried to import an gluster 
vmstore. I managed to import via NFS the former data domain. The problem 
is that when I moved the disks of the vms to the new ISCSI data domain, 
I got a warning that sparse disk type will be converted to qcow2 disks, 
and after accepting, the disks were moved with no error.


The problem is that the disks now figure as <1Gb size instead of the 
original size and thus, the vms fail to start.


Is there any way to recover those disks? I have no backup of the vms :-(

[ovirt-users] Re: Inconsisten datacenter [urgent]

[Juan Pablo Lorier]

Thanks. Sorry for the late replay but I had to travel. I've tried your 
suggestion and now I'm not able to start the engine VM. It's trying to get 
access for a storage (that I can't tell which is as vdsm only shows the ID and 
I don't have a way to know the label without the engine).
I think that I might need to hack into the database of the engine or reset it 
and hack in the backup so I can change some values by hand.
Any other ideas?

[ovirt-users] Re: Impossible to install VM Machine

[Juan Pablo Lorier]

Hi Abdoul,

what I don't get right is what is your setup. Ovirt can have data
domains that is where you put the vm disks.

That domains can be NFS share, gluster bricks, iscsi san or direct disk.
When you say files sharing folders, I can't think of a data domain
attached there unless it's a NFS local share.

Maybe I'm missing something, but I can see that working. Do you have a
data domain in storage? I tend to think you have because otherway you
can't create the disks for the vms (which you add when you create the vm)

Please, replay to the list too so others can see the thread.

Regards

[ovirt-users] Re: [ovirt-devel] USB on host support?

[Juan Pablo Lorier]

I'm having a similar problem. The passtrough needs 2 steps, the first is 
to attach the host device to the VM, but if you don't enable the spice 
usb the vm fails to start. I don't know if the USB works straight from 
the host device or if it depends on the spice console.


In my case, a device that work in a windows 10 pc doesn't work in a 
windows 10 vm.


Maybe we both can get help in this matter.

[ovirt-users] Re: USB Passtrough device problem

[Juan Pablo Lorier]

Hi,

I don't get what I should look. I can get the host module and then the
same in linux. In windows it uses the driver of the manufacturer. This
seems to be more something that I need to debug with the ovirt devs to
point out what I should trace. I don't know how to debug an USB stream.
What I can do is test the audio in the host and then see if it has a
difference in the passthrough.

Thanks!

[ovirt-users] USB Passtrough device problem

[Juan Pablo Lorier]

Hi,

I've tried to use 2 different audio IO interfaces connected to a VM via 
USB passthrough and none worked.


I've tried with win 10 and win server 2016 vms with different errors but 
none worked.


I've connected the devices to a host, then attached the host device to a 
VM and in the VM properties I've enabled the USB support in the console 
properties.


The devices are installed and don't show any error in the device manager 
within the VM, but they don't work.


Should I do something else?

Regards

Hi,

I'm trying to attach an USB device to a VM but although the host detects 
the USB device (is shown in lsusb), the host device tab in the VM is not 
showing that device. It show all other but not that one.


Is there something I should do to update ovrit host devices?

Re: [ovirt-users] vlan-tagging on non-tagged network

[Juan Pablo Lorier]

Hi,

My two cents is that shouldn’t be doing mac spoofing protection as a default. 
There are several use cases where you may use virtual nics defined withing the 
guest and this feature is going to create problems to users that may not know 
that there’s a mac spoofing protection withing ovirt.
Think of keeaplived vmac option, openvpn and any tap adapter you need to create.
If you need to protect against spoofing attacks, you should use the hook or 
more powerful tools and in any case, you must be aware that you used this kind 
of protection.

Re: [ovirt-users] separate ovirtmgmt from glusterfs traffic

[Juan Pablo Lorier]

Hi,

In my experience, having ovirt traffic on the same nic that gluster can 
make your platafrom unstable. I was using it for large file storage and 
gluster has so big traffic that ovirt got confused and started marking 
hosts as unavailable because of hi latency.
I've opened an RFE over a year ago, but had no luck with the team to get 
it done. In the RFE I was asking to have a way in the UI to decide which 
nic to use for gluster other than the MGMT net that is the one ovirt 
lets you use.
There's another way to do this and it's from outside ovirt. There you 
have to unregister and re register the bricks using gluster console 
commands. This way, when you register the bricks, you can specify the IP 
address of the spare NIC and then the traffic will not interfere with 
the mgmt.
There's a step that I don't recall much, but ovirt is going to need to 
know that the bricks are no longer is the mgmt IP, maybe someone else in 
the list can help with this. I can tell you that if you search the list 
you'll see my posts about this and the replys of those who helped my 
back then.

First thanks for the video. Though I have a question about the setup. I
don't see any options regarding multipath. You are connecting directly
to the iscsi lun, but most of the times the connection is redundant and
multipathd needs to be configured in order to have redundancy.
Is it a future enhancement or multipath is done behind scene? If it's
taking care of it, what about special configs for the device in the
multipath.conf?

Hi,
unfortunately the current setup doesn't support multipath. It's

Re: [ovirt-users] ovirt network VLAN tagging

[Juan Pablo Lorier]

Hi,

It seems to me that it may be a switch configuration problem. The vms in
the same host can talk to each other via the bridge, but if your switch
is not configured to allow tagged traffic for vlans 50 and 60 (and all
the way to the interface of the other host must allow tagged traffic for
those vlans), you won't be able to get traffic.

Re: [ovirt-users] oVirt + opennode or oVirt+proxmox

[Juan Pablo Lorier]

Hi Robson,

I don't know openode, but I can tell you that I can't think of a way of
using proxmox along ovirt. Both are virtualization platforms based on
KVM (so you can run vms from one platafrom into the other without any
conversion, just export-improt,copy or whatever you need to go from one
to the other).
They have both their upsides and downsides, basically IMHO, I like
proxmox decentralized way of managing the platform, but I love more the
great community around ovirt and it's fast evolution.
One thing is certain, your virtualization host can't be both, ovirts and
proxmox virtualization hosts.

 its a balancing act. but its also open source, which means anyone can

I'm aware of the open source nature of the project, my way of

 Hi Yedidyah,

 But If I run engine-setup and then engine-backup restore shuldn't it
 import the data to the existing db created by engine-setup?
 That's shown everywhere so I thought it's a valid way to migrate
 No.

 There is a specific case in which this works automatically:
 All on the same host:
 1. engine-setup
 2. engine-backup --mode=backup
 (perhaps do other stuff here)
 3. engine-cleanup
 4. engine-backup --mode=restore

 Why does this work? Because 'engine-cleanup', since 3.3, does not drop
 the database nor user inside postgres. So when restore tries to access
 this database using this user and password it succeeds.

 In general, if you do the restore on another machine, and do there
 'engine-setup; engine-cleanup' as a quick-postgres-provisioning-tool,
 you end up almost ready, but not quite - because the password is random,
 and therefore different between the installations. In principle you could
 have provided just the password to restore, but we decided that if you
 need to change the credentials, you should pass all of them (except for
 defaults).

 Hope this clarifies,

 Indeed, but this should happen automatically if you passed correct

 Is there a way to list the snapshots other than the webadmin?

 I had reproduced that in 3.4 beta 2 , can you please open a bug on that ?
 Thanks

 Eli
 If this is just Web UI issue than it is known for long time. But there's
 no clear reproducer (BZ was filled for RHEVM 3.3). This has something
 to do with Firefox cache. With clear FF profile snapshots are visible.
 But after some time when are not visible until full reload of the page.

 Rewriting /etc/ovirt-engine/engine.conf.d/10-setup-database.conf
 Note: you might need to manually fix:
 - iptables/firewalld configuration
 - autostart of ovirt-engine service
 You can now start the engine service and then restart httpd
 Done.

 $ engine-setup

 I believe I initially created the database incorrectly (ran 'createdb
 engine' as postgres user).  I was getting errors during engine-setup
 that indicated the database could not be accessed.

 After the steps above, everything looks good.

 Hi Yedidyah,

 No.

 There is a specific case in which this works automatically:
 All on the same host:
 1. engine-setup
 2. engine-backup --mode=backup
 (perhaps do other stuff here)
 3. engine-cleanup
 4. engine-backup --mode=restore

 Why does this work? Because 'engine-cleanup', since 3.3, does not drop
 the database nor user inside postgres. So when restore tries to access
 this database using this user and password it succeeds.

 In general, if you do the restore on another machine, and do there
 'engine-setup; engine-cleanup' as a quick-postgres-provisioning-tool,
 you end up almost ready, but not quite - because the password is random,
 and therefore different between the installations. In principle you could
 have provided just the password to restore, but we decided that if you
 need to change the credentials, you should pass all of them (except for
 defaults).

 Hope this clarifies,

Hi,

I've updated to 3.3.3 last week and now I find that the snapshots are
not shown in webadmin. I've taken some new ones to see if it was due to
the migration, but though they finish correctly, they are not shown in
the webadmin tab.
Is there a way to list the snapshots other than the webadmin?

[Users] Problems accesing the database

[Juan Pablo Lorier]

Hi Sahina,

Sorry to ping you directly, but you were of great help last time. I'm
also copying the list.
In the process of recreating the DC I've decided to migrate the engine
from a virtualbox vm to a bare metal host and I can't get engine-backup
to restore the engine.
Both are Centos 6.5 with engine 3.3.3, but in the new box I can't log to
the database with psql -U engine -W
The error is:

[root@centos-ovirt ~]# engine-backup --mode=restore
--file=/root/backup_20140212.bkp --log=/root/restore.log
Restoring...
FATAL: Can't connect to the database

I've added to pg_hba.conf the lines I found in the web:

hostallallmd5

and tryied with the conf from the one that works but nothing.
Any clues?

 Unlike engine-setup, engine-backup does nothing for you regarding
 creating the database - it's basically the same as creating a database
 to be used for a remote-db setup. See e.g. [1] for details, also
 'engine-backup --help'.

Almost, when you mean random password, you mean for the engine user in
the database?
The new install and the old differ in some things in the db, so I tried
to made then the same, but I saw a post of a user that removed the
engine database and user and created them again before trying to
restore, is that a good path?

OK, that did work. I droped the database and created it back and also
changed the password for the engine user.
That did the trick. I now have to figure out why the web is blank, but

Hi Sahina,

it's been some days since I got this to work thanks to your help. I
still don't have the time to seek trhough the logs to find when the
engine left things without erasing after the force deletion of the DC,
but if you wish, I can send you the raw logs and you may search in them.
Tell me if it's ok with you and I'll send you a google drive link.

Firstly, thanks for putting this information up!

Some comments -

1.  when you use different IP addresses for engine -to -gluster host 
(say IP1) and gluster -to -gluster communication (say IP2), operations 
from ovirt engine like add brick or remove brick would fail (as brick 
is tried to be added with IP1 which gluster does not understand)


To work around this, it is better to use a FQDN both for registering 
the host with engine and also to peer probe the host from gluster CLI.
You could have multiple IP addresses on the host resolve to the same 
FQDN.


2. To reuse a brick directory, gluster provides the force option 
during volume creation as well as adding bricks. This is available 
from gluster 3.5 upwards.

 The above would delete all gluster volume information stored in the db.

 Cluster information is stored in vds_groups table.

 You should have been able to remove the host using Force option.

 I think it would be safer to remove the host and then remove the cluster.
 You would have to remove the host entry from vds_static as well as
 vds_dynamic.

Re: [Users] Ovirt Gluster problems

[Juan Pablo Lorier]

Hi Sahina,

I've tried to remove the volume also from gluster manually to see if
ovirt would set it as inactive, but nothing.
The thing now is that as I was unable to remove the gluster domain, I
decided to force remove the hole data center and to my surprise, though
it deleted the DC and all it's data, it didn't delete the volume and is
still there in volume tab depending on a non existing cluster and thus
I'm not able to do anything with it as everything fails with there's no
host in the cluster
Sounds like the destroy operation is not checking everything and leaves
things hanging in the air.
Can you help me hacking the database to remove the volume? I'm in a rush
and can't wait till this bug gets solved (didn't open a bz as I'm too
busy right now).
I have a deadline to get this working by the 10th February and won't be
at the office from 4 through 6, so you may imagine where I'm standing.
I think the hole logic of dependencies in the gluster DC (maybe more)
must be checked as since I had my gluster domain down I was unable to do
mostly anything in the DC because everything depended on each other. I
couldn't delete the domain as there where vms in it, but couldn't delete
the vms as they needed the domain. Couldn't remove the hosts as they
where bricks, but couldn't remove from the volume as the domain was
down, etc, etc

I'd like to say that though setting ovirtmgmt as non vm as a default
should be nice, it won't be enough as it won't allow to use mixed
traffic in other interfaces either, so the way I see it, the fix should
be to add this ability to ovirt. I can't make my mind to think what a
big corporation may need in security restrictions, but as a small
company, I'm willing to take the risk of a hardly probable security
breach in favor of been able to use untagged and tagged vlans on the
same nic.

 1. yes, too many issues on this one, hinting we should provide better
 text explaining this in the UI.

 2. the bug you referenced[1]
 Bug 1049476 - [RFE] Mix untagged and tagged Logical Networks on the same NIC

 is actually supported, as long as the untagged logical network is not a
 VM network (so VMs associated with it would not be able to see/create
 other logical networks traffic).

 3. considering how prevalent this is, maybe we should allow doing this,
 even for VM networks, with a big red warning, rather than block it,
 which seems to be failing everyone.
 Besides that it's technically not possible in the way we currently use the 
 Linux Bridge [1],
 I'm not sure what's to gain from representing a single flat network with 
 multiple representations.

 Seems to me like there may be a couple different points here:
 * ovirtmgmt is VM network by default - should be configurable on setup and/or 
 DC creation.
   If it's such a prevalent issue, we should consider a default of non VM 
 network (users can create a flat network and use it quite easily anyway, if 
 they want).
 * if people want to represent different L3 networks on the same L2 network, 
 it is worthwhile to design a proper solution

 Either way, I wouldn't push for allowing multiple bridged networks on the 
 same physical interface (or bond).

Re: [Users] networking: basic vlan help

[Juan Pablo Lorier]

Hi Robert,

You can use mgmt untagged but if it's a non-vm network. If you tag mgmt
network, ovirt will configure a vlan interface and add it to ovirtmgmt,
so you'll get a disruption when network gets restarted to take the changes.

Re: [Users] networking: basic vlan help

[Juan Pablo Lorier]

Hi Robert,

As I said before, you'll have network disruptions everytime you change
network topology and that's not because of ovirt but because you need to
restart network to set the new interfaces, routing tables and addresses,
etc.
This does not mean that you loose access to your hosts, if everything
goes right and you have everything set correctly, then after network
comes up, you should have access to your hosts. But if you have network
traffic, it will loose connectivity for a few seconds.
For the switch stuff, a simple switch will forward all packages
regardless of the vlan tag, so you won't need to configure anything.
These are the domestic or soho kind of switches. If you have a vlan
aware switch (most managed cheap ones have vlan features), then you'll
have to set vlans (either tagged or untagged) in the respective ports to
be able to get traffic from them.
Remember that marking a network in ovirt as a vlan network means that
it'll be accepting tagged traffic from that vlan. If you set your ports
to have a native vlan (untagged), then you should use non-vlan networks
in ovirt.

[Users] vlan on mgmt network

[Juan Pablo Lorier]

Hi William,

You can have several logical networks on the same interface. If
ovirtmgmt is not a vm network you can even mix tagged and untagged
networks (if not, you can't mix). You don's have to do anything besides
creating the logical networks in ovirt and assign them to the interface,
ovirt takes care of creating the virtual interfaces it needs.
What you can't do is have more than one logical network per vlan (I
think there's a feature request on this, I know I've asked it on the
list:-) ).

Yes. Also other LN where out of sync, but the hosts had differences in

 3. Do I understand correctly that even though it's marked as
 out-of-sync, you don't see the synchronize checkbox when editing the

It doesn't. I made some tests and I found that it's a problem with
firefox (mine is version 26 over Fedora 19). It's showing things a
little bit bigger than chrome and so the sync option is not shown in the
edit window. Other functions also are not working properly, for
instance, if I choose a particular item into a category (host, vm, etc)
in the left tree, the right frame does not change, I have to choose the
group (hosts, vms, etc) and choose the particular item among all the
listed in the right frame. I've checked and firefox 22 on windows has
the same behavior. This started to happen after I upgraded from 3.3.0 to
3.3.1 but never saw the lack of the sync option until now.

Re: [Users] Networking questions (LONG)

[Juan Pablo Lorier]

Hi Dan,

I take the chance to ask; why is that the untagged IF can see the
traffic of the tagged vlans? Isn't that filtered at kernel level? Is
this a virtualization design limitation or is it down to the kernel?
I don't know how the kernel processes the packages, but I thought that
packages that arrives to the nic are filtered by the kernel and sent to
the respective vif (untagged to the master interface and tagged to the
.XX interfaces). I ask because other virtualization platforms don't have
this limitation and I wonder if it's because they don't care of
because they solved this somehow.

 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.
 This was devised as a security constraint - otherwise, a VM attached to
 the non-VLAN network could sniff traffic from another (VLAN) network.
 However, it seems that this is exactly what you need - a special VM that
 is designed to do just that.

 And it's not only you: there's another recent request for lifting this
 limitation:
 Bug 1049476 - [RFE] Mix untagged and tagged Logical Networks on the
 same NIC

 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
 I do not understand what you are trying to do with dummy devices (after
 all, they are not going to send any packet anywhere).

 But if you are willing to mess with network configuration under the feet
 of oVirt, you could do the following:
 - create a network tagged with an id that is not really used in your

 Ahhh yes, I recall the problem now (thought it might be possible as long

 (assuming the VLAN interfaces are still intact on the hosts, as I deduce

Re: [Users] Network not sync and problems reconfiguring

[Juan Pablo Lorier]

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 Dan,

If my opinion is worth, I use logs all the time as my setup is evolving

Re: [Users] Attach nfs domain to gluster dc

Hi Sergey,

Sorry for the delay, but the holydays got in the middle. I've tried copy
the images among the domains, but I've got the new domain corrupted
(copied more than I should I guess). I'm trying now to learn to use
ovirt-shell as Itamar pointed to see if I can get this going.
If it make sense to you, I can open an RFE to get the option to modify
an existing domain.

 Hi Sergey,

 No need to apologize. I'm used to hear that iso domains need to import
 the images, that just copying them won't work. I thought export domains
 were the same, but if you say I can just copy, I'll try that next Friday
 when I come back to the office.
 I think this is the easier approach as using the REST would mean that I
 have to learn to use it and it's not the right time of the year :-).
 I think that been capable of modifying the options won't heart anybody
 and looks like harmless, at least when domain is in maintenance, you may
 say if I'm wrong.
 Thank you very much for your help and for your disposition.

 I apologize for discovering this thread with delay. Let me try to explain.

 Attach option indeed missing a possibility to configure NFS options such as
 nfsver, retrans and timeo
 which by the way available when creating a new storage domain (see the
 Advanced Parameters section).
 I have to check this flow again and see which storage connection we use in
 order to connect this storage to the new data center. If this is a bug
 we'll fix it.

 Now about the default NFS version, we are using version 3 because usually
 customers have a problem to configure NFS server version 4 properly so we
 allow using version 4 as an advanced option.

 Now about your problem:

 Option 1:
 Can you just create another Export Storage Domain from scratch using
 advanced parameters I mentioned above in order to configure the NFS
 version and then just copy the content between these domains manually.

 Option 2:
 You can try to create new storage connection with the REST API as explained
 here: http://www.ovirt.org/Features/Manage_Storage_Connections and then
 try to re-attach this storage domain again.
 Or we can just update storage_server_connections table manually in your
 database.

 I never tried option 2 by myself but it should work.

 Please, feel free to contact me on my direct mail tomorrow
 sgot...@redhat.com and I'll walk you through one of these options and we
 can check you NFS configuration.

Juan - you shouldn't have to learn to use the REST API directly. all 
of it should be available via ovirt-shell - a command line tool (as

Re: [Users] simple networking? [SOLVED] mostly

[Juan Pablo Lorier]

Itamar,

I have the same problem and already have mentioned that in previous
posts. In my case, I have vlan 128 tagged assigned for ovirtmgmt so I
set the host ip manually on top of a vlan interface and the, after ovirt
does install the node, it fails to finish as it can't manage properly to
create the bridge and pass the ip to the brand new bridge. The ovirtmgmt
interface I create in engine is a bond (and originally I configure just
a single interface with the ip to grant engine access), just in case
this changes the scenario.

less but often, errors of not been able to call async, I'm I missing any

Is there a way not to log all the VolumeList commands (without lowering
log level) to avoid having so many entries that difficult searching in

Hi,

I'm finally starting to pis off with ovirt 100 steps and locks. As I
can't modify the export domain while it's in maintenance and while it's
active I can't change the version, how should I get rid of the v3
limitation on this existing domain?
Can someone tell me why ovirt defaults v3 and not 4? is it something to
do with existing bugs or limitations?
Can you please put as much energy in make things easier as you put in
new features? Not a critic but a request.

[Users] Attach nfs domain to gluster dc

[Juan Pablo Lorier]

Hi,

I've created a new DC in order of been able to create vms on a glusterfs
data domain. As ovirt does not allow to share export and iso domains
between DCs (nice RFE) I detach those from the actual DC and when I try
to attach them to the new DC, I get an error:

Re: [Users] Using storage network for gluster

Thanks Gianluca, I'll try that. I still am under testing for this
gluster cluster, so I have no problem with downtime. :-)
I'll let you know what happened.

 Now I'm having ovirt to complaint about a network error in the volume

 iscsi?
 - What may be the problem with network?
 this worked for me after default install that, as you already wrote,
 doesn't allow to have anything but the ovirtmgmt.
 Of course it needs downtime... suboptimal...
 see this thread of mine:
 http://lists.ovirt.org/pipermail/users/2013-October/016891.html

 Using ovirtmgmt I had problems with cluster due to ovirtmgmt saturated
 if I had heavy I/O on VMs (so network bandwith from gluster point of
 view)... with hosts going into non operational status.
 No problem after changing network.

H,

I get success on both hosts when I proob each other

# gluster peer probe ovirt4.montecarlotv.com.uy

Re: [Users] Using storage network for gluster

Well,

It seems that I rushed into the list as I finally managed to get the
volume up.
It was a mix of things, had to restart glusterd in both bircks, then
following
http://joejulian.name/blog/glusterfs-path-or-a-prefix-of-it-is-already-part-of-a-volume/
that pointed a solution for a possible bug in gluster 3.4 I managed to
get things working (I had tried before but didn't work, seems like
restarting glusterd made it possible)
Thanks and sorry for so much noise.

 Contrary to my other post, which was more educational than practical,
 yes, you generally would not back up app data via a hypervisor
 snapshot.  Generally you would only backup the OS disk and perhaps the
 application binaries.  This would be for quick restore of the OS and
 app, so you don't have to spend hours reconfiguring your OS. 
 (especially Windows based OSes)

 I also do an IN OS backup as well, for individual file restores in the
 instances you accidentally destroy something in /etc for example.

Re: [Users] simple networking?

[Juan Pablo Lorier]

Hi Ted,

I've lost the beggining of the thread so excuse me if I'm wrong about
the topic.
Do you want to get all the vms and host in the same subnet as the rest
of your lan or the hole collision domain?
When you create the logical networks (LN) in ovirt you can check if they
are required or not. If you decide that all your hosts must give access
to some subnet for vm use, you can create a LN, mark it as required in
your data center (DC) and configure it in every host you have in the dc.
Then you have two choices, if you just want the vms to access that
subnet, add it to the host without configuring the ip on the host and
you'll just get a bridge for vm use. If you want the host to use the
bridge also, configure the ip and you'll get both, vms and host to be in
the subnet.
If what you need is to get every vm access to the hole collision domain,
then I don't think you can do it in ovirt as you get a bridge for every
logical network and if you have both, tagged and untagged vlan traffic,
you won't be able use the same nic (or bond) to place mixed LNs (a
limitation I've rised but yet haven't been resolved).
Hope this helps.

 Currently we do not update the size of the LUN in the db.
 Please file a bug on this as in 3.3 we already retrieve the lun info on

 You can extend SD with additional LUN instead (Map new LUN - SD - Edit
 -
 check new LUN).

 You can try to re-elect SPM for now.

Re: [Users] Resizing the iscsi data domain

[Juan Pablo Lorier]

Hi,

I did try to put the sd to maintenance and back to active as Eduardo
pointed before but it didn't work. That was with engine 3.2, today I'll
try again with engine 3.3 to see if it behaves the same way.
I'll let you know the results.
Regards,

[Users] Export not exporting the disk

Hi,

I've already posted before but the thread went dead. If I export a

Hi,

I know that now there's a doc in google drive for this, but I don't have
write access so I post this here:

I need to backup my vms that use direct-luns as disks and neither
snapshot nor export do the job, so I propose at least one of those

Re: [Users] custom multipath.conf

Thanks, I thought ovirt had something as it pushes the multipath.conf in
the host deploy (overwritting my config). I may dig into puppet as it
may also help in provisioning bare metal hosts.

 No such centralized mechanism exists within ovirt. However you could use
 the likes of puppet to do that, or write a short before_vdsm_start hook
 that pulls multipath.conf from a well-known location.

Re: [Users] Problems with snapshots

[Juan Pablo Lorier]

Thanks Itamar,

The thing is that export doesn't copy the direct lun. About snapshots,
can it be done if the lun has lvm? I used to make a sort of live backup
using lvm snapshots with this luns, maybe this can be done within ovirt
in a future version.

 Another thing is that it looks like you had the vm started from a disk
 in the data storage, mine are from direct lun.

 Anyway, I'm trying to make backup from the vms by cloning the vms and
 exporting them, but even exporting a shut down vm does not copy the
 disk.
 Is exporting of a direct lun possible with ovirt?

 so as explained, snapshot are currently not supported for shared disks
 and for direct lun disks.
 export of direct lun disk should work though.
 allon?

Re: [Users] custom multipath.conf

[Juan Pablo Lorier]

Can it be a proposal for a new feature in ovirt 3.4?
I think that is rasonable to have one place in ovirt where you can
configure your targets and alias as every host that may need to access
those targets should have the same config.
