That's because all oVirt documentation is community driven. This specific page 
was written by a guy I happen to know quite well (I wrote it):)

This was written back when there was no easy to install package, where you had 
to do that by hand, and if you want to, you still can, the method still works. 
But I agree that if there's an easier way today, I think we should go with that 
first and keep this compiling method as the fallback.

ZFS is definitely pretty awful at keeping your data _unsafe_ : )

Add a piece of the SSD's as mirrored SLOG and be both safe as fast. My
two cents.

[ovirt-users] Why/how does oVirt fsync over NFS

[Karli Sjöberg]

Hello!

This question arose after the (in my opinion) hasty response from a user
that thinks oVirt is bad because it cares about the integrity of your data:

https://lists.ovirt.org/archives/list/users@ovirt.org/message/QPVXUFW2U3WGJF2FP3ALBPXJGRJS76YE/

Fine, that's their choice. They can have silent data corruption all they
want in case of a power failure or something, it's up to them if they
think it's worth it.

However, I started wondering why oVirt sync's everything over NFS, I
know it does because you can in ZFS turn it off by "zfs set
sync=disabled " and throughput and everything goes through the
roof. The right way is of course to add a SLOG or better yet a mirrored
pair but just for a quick test or whatever...

But their doesn't seem to be any reason why oVirt should do that, that's
why I'm asking. Look, this is from the CentOS 'mount' man page:

"defaults
  Use default options: rw, suid, dev, exec, auto, nouser,
and async."

So therefore 'sync' should be explicitly set on the mount, right? Wrong!

# mount | grep -c sync
0

So why then does it sync? The NFS man page says:

"The sync mount option
   The NFS client treats the sync mount option differently than some
other file systems (refer to mount(8) for a description of the generic
sync and async mount options).  If  neither sync nor async is specified
(or if the async option is specified), the NFS client delays sending
application writes to the server until any of these events occur:

  Memory pressure forces reclamation of system memory resources.

  An application flushes file data explicitly with sync(2),
msync(2), or fsync(3).

  An application closes a file with close(2).

  The file is locked/unlocked via fcntl(2)."

So which of these things are happening for the Host to send sync calls
to the NFS server?

Just curious...

Thanks for the reminder Sandro, I had missed that!

I'd like to see another choice for how often you upgrade, namely
"Whenever the current release reaches EOL" :D

I know it's bad form and I'm missing security updates and stuff but
getting on the "current train" has been way too unstable and bug-ridden
for me. I intend to live on with 4.2 until 4.3 goes EOL and then upgrade
from there in my environment. To test out new features and such, I have
a nested virtual cluster living in my laptop that I kick up now and then
to test upgrades, features, bugs-fixes and so on.

As always, thank you all for the amazing work you do! Don't you dare
stop doing it! :)

Heyo!

Not that the thread is about ZFS, but I find this "stop and go" behavior
interesting.

FreeNAS is a excellent NAS platform, I mean, it's in the name, right? ;)
However, the ZFS filesystem and how you configure the system does impact
performance. First of all, how have you configured the drives in the
zpool? RAIDZ is not recommended for virtualization, just because it's
random IOPS performance are set to 1 HDD/vdev. If we assume a SATA drive
has 150 random IOPS and you create a 8 x 6 TB RAIDZ2 vdev, that entire
pool only have 150 random IOPS total. Can you do a "zpool status" and
post the output?

Second, it's worth mentioning that block sizes still matter. Most drives
still lie to the OS that they are 512 byte sectors while really being
4k, just so that older OS'es don't freak out because they don't know
drives can have any else than 512. I don't know if FreeNAS solves this
issue for you but it's something I always take care of, either by
"sysctl vfs.zfs.min_auto_ashift=12" or trick ZFS into thinking the
drives are true 4k disks with "gnop". A way to check is "zdb | grep
ashift"; it should be 12. If 9, you may have worse performance than you
should have, but not way worse. Still... Then there's alignment that I
also think that FreeNAS takes care of, probably... Most systems place
the partition start at 1 MiB which makes it OK for any disk regardless.
Your disks should be called "adaX", run "camcontrol devlist" to get a
list of all of them, then pick one disk to check the partitioning on
with "gpart show adaX". The "freebsd-zfs" partition should start at
something evenly divisible by 4096 (4k). Most of the time they're at
2048, because 512*2048=1048576(1MiB) and that divided by 4k is
(1048576/4096=256), which is a beautifully even number.

Third and maybe most important, ZFS _does_ listen to "sync" calls, which
is about everything over iSCSI (with ctld) or NFS. That means, since
your hosts are connecting to it over one of the two, for _every_ write,
the NAS stops and waits for it to be actually written safely to disk
before doing another write, it's sooo slow (but super awesome, because
it saves you from data corruption). What you do with ZFS to mitigate
that is to add a so called SLOG (separate log) disk, typically a
hella-fast SSD or NVME that only does that and nothing else, so that the
fast disk takes all the random, small writes and turns them into big
streaming writes that the HDD's can take. You can partition just a bit
of an SSD and use that as a SLOG, typically not more than the bandwidth
you could maximally take, times the interval between write flushes in
ZFS, which is 5 secs. So 10Gb/s is about 1,25 GB/s, tops- and you have
two of those. 2,5GB*5 = 12.5GB. Which means 14GB should definitely cover it.

Lastly network, are you sure you activated jumbo frames, all the way
from the storage to the hosts? That makes a huge difference on 10 Gb
ethernet. A way to test this is to start tcpdump on the iSCSI/NFS
storage interface, looking for just ping, like "tcpdump -vnni Jumbo_NFS
icmp" on both the storage and a host system. Then from another terminal
(as root) of the storage or host, send just _one_ big ping packet, and
see what you get, like so: "ping -c 1 -s 8192 XXX.XXX.XXX.XXX". The
tcpdump output should just have recieved _one_ ICMP echo request and
sent back just _one_ ICMP echo reply; one to get there, and one back.
That's how you're sure you've got no fragmentation happening between the
storage and host.

I swear, I didn't mean to write a book about it, it just happened :) You
put a quarter in the ZFS box and this is what you get...

Correct me if I'm wrong, but I think that your statement is true *if* the networks are set as mandatory, which is not automatically wanted nor true. In our case, we have to disable this mandatory attribute.Correct. I took a hasty look at the logical networks page[*] and didn't see any mention of it and thought they must've removed that option.Can you still do that? Doesn't make much sense to me, purposely having non-operational/unavailable hosts in a cluster due to network incompatibility.../Khttps://www.ovirt.org/documentation/admin-guide/chap-Logical_Networks.htmlI agree that when the networks are mandatory, every host unable to use them will end up unavailable.> Different networked hosts needs to be put in a separate cluster.> > /K-- Nicolas ECARNOT___

Maybe a dumb question, but have you tried to press any buttons on the

[ovirt-users] FW: [ovrit-users] Anyone with Fiber Channel oVirt Storage Experience?

[Karli Sjöberg]

Hey G!Didn't you write some time ago that you used FC storage? Perhaps you can answer Jacob's question.../KDen 14 nov. 2018 16:39 skrev Jacob Green : I just have a few simple questions, have you migrated a fiber channel storage domain from one ovirt environment to another? And how did it go, did it just work aside from having to import all the vms and configure their settings was it any more difficult than that?We want to migrate our fiber channel storage with VM's intact from an oVirt 4.1 environment to a brand new oVirt 4.2 environment.We are using fiber channel via An HP MSA. I do not for see any issues, but since we have never done it before, and we do not have spare Fiber Channel storage to test with, we are just unsure of what the behavior should be. So just wanted to get some opinions or basic guidance, is there anything we should watch out for and does it "just work".-- Jacob GreenSystems Admin713-300-5690___Users mailing list -- users@ovirt.orgTo unsubscribe send an email to users-le...@ovirt.orgPrivacy Statement: https://www.ovirt.org/site/privacy-policy/oVirt Code of Conduct: https://www.ovirt.org/community/about/community-guidelines/List Archives: https://lists.ovirt.org/archives/list/users@ovirt.org/message/R3MO5G4BC3XD4B2QMHPTPK7QEIKY4TZF/___

OK, no that is not supported. I mean, it was a long time ago but not
any more. I wouldn´t worry about the engine being a VM, it´s acutally
very stable, net positive compared to having it physical, in my
opinion. And more available compared to having hardware outage.

What I would do is set it up as three node hyperconverged and then just
remove "Machine1" from the "Hosts" interface, so it´s not used for
compute.

Usually you´d want to deploy oVirt/Gluster "hyperconverged"[*] with
three machines. Hyperconverged means that the servers are deployed both
for compute and storage at the same time, and the engine is a VM in
it´s own cluster (it doesn´t have to be a separate server).

Or is this something you really don´t want? If so, why?

Hi Miguel,
  
  Thanks for getting back to me so quickly! The pastebin

Ooh, that is really cool, I had no idea that was
  even possible! I've gotta ask though: why? Is it to have
  switch redundancy without having to shell out the extra price
  of having the switches stackable?


/K
  

Yes, that is exactly why, and that the servers I have contain 2 x 4
port gigabit nics in each of them. At work we've been consolidating
some of our systems and I got a bit of old free kit which I'm aiming
to use to set up a home lab based on ceph (with the new iscsi
gateway) and ovirt. The swtiches I got are fairly basic and don't
stack, but I wanted to achieve redundancy throughout so this is the
reason for trying to do it with a bond of bonds.Yeah, for your use-case that makes total sense. And kudos for playing with Ceph, we're thinking of going that route with iSCSI GW, but for VMWare instead.For large deployments though, I think it's still going to be about as expensive as you'd need to double the amount of ports needed, don't you agree?/K

  



  

  

  Thanks

Daem, thanks for the heads up! I was thinking
  about updating but now I'll hold that off for sure!


What version FreeBSD are you using?


Is this issue reported?

Wesley,

Windows reportes about 500-600 MB/s over a 4GB file.


However I believe I found the issue.  My NFS backend is ZFS which is apparently notorious for horrible sync writes.


https://forums.freenas.org/index.php?threads/sync-writes-or-why-is-my-esxi-nfs-so-slow-and-why-is-iscsi-faster.12506/



I will try an iSCSI target and see how that goes.You don't say! Well ZFS just happens to be a love of mine, you're in luck!:)In that case, and since you're clearly disregarding my previous warning about how fsck'ed up you'll be when shit hits the fan about asynchronous writing then I can tell you that the article is referring to the old 'istgt' daemon that never even listened to sync calls, something you'd normally want if you care about consistency. Nowadays, that has been replaced by 'ctld' which is far superior and does listen to the calls, so no, you won't see any difference there. What you can do to force ZFS not to care is to:# zfs set sync=disabled After that it won't matter what the services want any more...Now that I've spent my time telling you what you shouldn't do, aka it'll get you in trouble sooner or later, I feel obligated to tell you what you should do, instead:)The right thing to do is to add an SSD to your pool as a SLOG (Separate LOG) that'll take care of all those pesky sync calls that normally slows you down. A pro tip is to just use a small partition of a bigger disk, helps the drive relocate sectors that are damaged over time, say 15 GB partition of a 256 GB SSD will last a life-time and even if it doesn't, it's ok if it dies, it'll just be as slow as without it, you'll surely notice and know to replace it:) As a big bonus, it'll also help prevent fragmentation moving the ZIL (ZFS Intent Log) out of the main pool onto the SLOG.Good luck with it!/K

Or If I copy and paste ISO from the VM to itself, horrible performance.


If I grab a file from a VM on my raised SSD storage and copy it to my VM on the NFS Share, it has great performance (400+ MB/s)


Not quite sure what's going on!  However if I grab something from the 1gbps network everything seems okay.  Or if I change the NFS Mount to the 1 gbps everything is okay. 


Any ideas?









Let's start with expectations, shall we? 10Gb ~ 1 GB/s. So you read a file over SMB and write that to a VM hosted on NFS, so remote to remote. The absolute max for that transfer would be ~ 500 MB/s. What do you get?

My single node oVirt host has a mirrored SSD store for my Windows 10 VM, and I have about 3-5 VMs running on the NFS data store.


However, VM/s on the NFS datastore are SLOW.  They can write to their own disk around 10-50 MB/s.  However a VM on the mirrored SSD drives can get 150-250 MB/s transfer speed from the same NFS storage (Through NFS mounts).


Does anyone have any suggestions on what I could try to speed up the NFS storage for the VMs?  My single node ovirt box has a 1ft Cat6 crossover cable plugged directly into my NFS servers 10GB port.

It may be because of how oVirt mounts them, much more carefully, than Linux does by default. If I am not mistaken, oVirt mounts the NFS shares with 'sync', whereas a standard 'mount' with no options gets you 'async'. The difference in performance
 is huge, but for a reason; it's unsafe in case of a power failure. That may explain things.

In my case it's Xubuntu 18.04 LTS. Is there anything I can do to help
out with this?

That is exactly the same thing that happened to me today! Could you try
deploying again and in another terminal run this[*] after it's printed
"Get local VM IP"?

What happened to me was that the VM never started because it had kernel
panicked on boot, rather fast too, so you'll need to be quick in order
to catch it!

[*]: virsh console HostedEngineLocal

PS. The console will then hang if we're experiencing the same issue.

[ovirt-users] Hosted Engine Deploy kernel panics on boot

[Karli Sjöberg]

Hey all!

I'm trying to deploy Hosted Engine through the Cockpit UI and it's
going well until it's time to start the local VM and it kernel panics:

I've never had this problem so I'd just want to know if it's a known
issue right now or if I've done anything special to deserve this:)

The "Hosts" I'm deploying this on are VMs with nested virt activated,
and I've done this before but this time around it's bombing, as earlier
explained.

Thanks in advance!

Well, thank god for that! If it was running on more than one node at a
time, it would write itself to pieces!

But seriously, what´s the problem? What you´re describing is exactly
how it´s supposed to be:) And for what it´s worth, do yourself a favor
and upgrade, 3.4 has been EOL for a looong time now.

I can't remember all of the gotchas I had to go through but most of them stemmed from the fact that I tested it all on a three node oVirt HCI cluster that was actually VM's with nested virtualization, which meant fairly limited resources but eventually got it working.Being completely new to OpenShift, a guide that needs more work is the single sign on from oVirt to OS. The instructions are way too unclear for me, and wrapping your head around how the login and permissions system works in OS took a while, to create an equal 'admin' account to log in with.Second, isn't OS just an above layer of kubernetes under it, or is that a misunderstanding on my part? If it is though, where is the administration page for Kubernetes in all of that? I'm thinking in the sense of how you can add more nodes to continue building a larger cluster for containers.OpenShift is much more than just Kubernetes, but specifically this instance should be used solely for metrics and logging and is therefore specifically installed as an all-in-one installation. Y. OK, yeah, for sure! But is there no Kubernetes console in this all-in-one installation?/KBut once everything was setup and able to log in to the Kibana interface and loading up the dashboards you've made, I was really impressed with how much data you got visualized for free.

    Hi Karli Sjöberg:
  May be you still using oVirt-4.1 so no problem but I am sorry
  could not agreed with "nothing wrong with oVirt", if nothing is
  wrong why I use FreeBSD 10.3 installation CD could boot and even
  finished the installation but not for FreeBSD 10.4 and 11.Yeah, no, I worded that wrong, of course it is a regression. What I meant was that something most likely has changed in how oVirt is starting the VMs that is causing this. A good start would be for you to compare the VM XML from 3.6 to what you have now, 4.2 was it? So you can file a bug report to give the devs something to look at.My hunch is that unfortunately not at alot of people run AMD clusters which then don't get as much "love" as the other. Hopefully this'll change to at least a 50/50 attention as AMD takes more shares of the market, but it won't do any good for your old Gen 3 Opterons, so don't hold your breath hoping for it to just fix itself, you'll have to really push the devs to do something about it!Good luck with it!/K
  As all my Host is AMD based, so no idea how to test further, May
  be I will try to reinstall oVirt again to see does it work and
  report again.
  Remark: I could even migrate FreeBSD 10.2 and 10.3 to this
  oVirt-4.2 but surely could not install new or migrate 10.4 or 11

So the image says the virtual hardware is about the same, except for Cluster type. I've had issues before getting FreeBSD running in oVirt with Opteron. Since i then had two clusters: one AMD and one Intel, I worked around it by only using the Intel cluster for FreeBSD guests.I also tested booting FreeBSD ISO on the host metal (old Sun Fire, maybe X4440, something like that), so it should just be a oVirt/QEMU thing, but I never tried fixing it./K2018-05-30 2:06 GMT+08:00 Karli Sjöberg <ka...@inparadise.se>:On Wed, 2018-05-30 at 01:09 +0800, Paul.LKW wrote:

I just tried it as well, works fine, no problemo. My VM has:
1       vCPU
1GB     vRAM
8GB     vHDD

In a Nehalem cluster.

Alex, Paul, what´s yours?

Big thanks, now I understand what the problem was!

But I must say, after reading that thread, I´m actually more interested
in setting up the metrics store as it seems you get way more data out
of it without having to access the database directly. The point being,
the less manual stuff you do to alter the original setup in the engine,
the less issues you are going to have later on, with upgrades and such.

[ovirt-users] oVirt reports using Grafana

[Karli Sjöberg]

Heya!

I've been whishing for reports in oVirt ever since the old 'Jasper
Reports' was removed. For an Enterprise, having pretty graphs to look
at is a must.

Searching the subject, I've found this[*] and have managed to get it
installed OK but having issues trying to follow the guide setting it
up.

First of all, I think the guide should have at least mentioned that
'pg_hba.conf' needs to be edited for the read only user to be able to
connect to the database, I scratched my head around that for a while
before I got it.

When I first type in the query example, I got syntax errors:
'pq: syntax error at or near "$"'. I continued anyways since I figured
it would be solved at a later point, which turned out to be true, since
the next step is to use the "Templating feature" to add variables.

Unfortunately this doesn't go so well, even though I followed the
instructions very carefully. After hitting save on the first variable I
am rewarded with the error message:
'Template variables could not be initialized: pq: column "en_us" does
not exist.'

Are the queries stated in the guide still correct? This is for
'user_locale':
"SELECT DISTINCT language_code from enum_translator"

Hijacking this a little, because I got curious about something:)

Is it possible to do regex searches? Because I remember working on
something different, the searches could potentially end up with
multiple matched objects, like "thenameofclonnedvm",
"thenameofclonnedvm-berta", "thenameofclonnedvm3" and so on. So I was
always forced to treat the result as a potential array, loop the
objects (this was with Python) and test for an exact match, even if it
was just one object. So it would be nicer if you could go like:

api/vms?search=name='^thenameofclonnedvm$'

And be sure to have an exact match every time. Is that possible?

There aren´t any specific documentation about using ZFS underneath
Gluster together with oVirt, but there´s nothing wrong IMO about using
ZFS with Gluster. E.g. 45 Drives are using it and posting really funny
videos about it:

https://www.youtube.com/watch?v=A0wV4k58RIs

Are you planning this as a standalone Gluster cluster or do you want to
use it hyperconverged?

Feels to me like OP should try to get it working _any_ "normal" way
before trying to get the special use case application working?

Like trying to run before learning to crawl, if that makes sense?

I would suggest just logging in to webadmin with a regular PC and
trying to get a SPICE console with remote-viewer to begin with. Then,
once that works, try to get a SPICE console working through moVirt with
aSPICE on an Android phone, or one of the Chromebooks you have to play
with before going into production. Once that´s settled and you know it
should work the way you normally access it, you can start playing with
your special use case application.

Hope it helps!

Dear oVirt.
 
Executing engine-config –s ClientModeVncDefault=NoVnc does not result as expected.Did you restart the engine after you made that change?/K
 
Even though command is executed, I cannot find the VM console setup (during creation) which sets noVnc as default, it’s always Native VNC.
 
Any advice?

I suppose that power saving policy should converge VMs into hosts one by one. Something like that.

With many VMs activated, exceeding the threshold, power saving scheduling module should turn on another host…Jepp, that's basically how it works:)/K If anyone had played power saving scheduling policy, please share me your scenarios or some hints.

If we do decide to limitthem at all, I'd limit only in a negative way - what's notallowed. E.g. it makes sense to me if we reject prefixes thatare common for non-bonds (eth, en, wl, br etc), but even thatI am not sure is so important.I agree, while at the same time, I don't understand why you would want to "label" a bond. Even if it's untagged, since you can label the bridge that's ontop of it? So even if the bond is called "bond0", the bridge can be called "data", or whatever, to ease diagnozing etc.What if it's tagged? Would you want to label both bond, vlan and bridge? Like "foobond", "barvlan" and "bazbridge"?/K

I see that you are trying to use a bond interface named "mgmt".
To avoid confusion while debugging a system, Vdsm has opted to allow
only bond names starting with "bond" followed by one or more decimal
digits. Anything else is considered "bad bond".

I prefer keeping the "bond" prefix compulsory, but I'd like to hear
why using different names is useful.

You can reopen this bug, but please move it to vdsm and rename it: it
should be something like "Allow any bondXYZ name for bonds" or "Allow
any bond name" and explain there why it is a good idea.

Dominik, is there an Engine-side limitation on bond names?

Eh, NP!

So my thinking is to keep hacking it to make it more feature complete
and see if I maybe can get the code accepted, then, starting from a
suitable release, try getting it into ports.

But it´s not something I´m working especially hard on, just for fun. So
don´t expect too much too soon.

Firstly I need export (with a gigabit nic) to export domain, and back under 10gbe nic.I don't know how is enough this.Well, just counting the numbers, let's start with the optimistic approach and say that you can move 100 MB/s for 8 hours:100*60*60*8=288 MBAnd then just divide that with 1024*1024 to get to Tera:288%(1024^2)=2.74658203125 TBSo roughly 2.7 TB in 8 hours, and that's very optimistic! If you're more pessimistic, adjust the number of MB you think (or better yet, tested) that you'll be able to send per second to get a more accurate answer.The question is how much you can do without any downtime, I don't know myself, but the devs should:@devsIs it possible to do live exports?

You know, the state the VM _was_ at in March is really different to
what it is now anyways. I would just turn it off and "Commit" the "now"
state inside of the VM to it´s Current snapshot. I´m having a hard time
seeing how the state from back in March would be relevant today.

Or, you turn it off and "Undo" the operation just to get the March
snapshot back as it was, but you´ll lose how it looked like from before
you turned it off.

It plague or cholera I´m afraid, since one of these things _has_ to
happen for you to continue.

You´ll need to build the Gluster storage first, as you´ll want to
install the Hosted Engine _in_ the HA Gluster storage, right?

Mobile devices don't have a right click, so hiding functionality in there would make no sense.- You can now right click and get the browsers menu instead of ours and you can do things like copy from the menu.- We replicated all the functionality from the menu in the buttons/kebab menu Hold on just a minute, we should really pause and think about this for a while.

Our goal was to have all the commonly used actions as a button, and less often used actions in the kebab to declutter the interface. We traded an extra click for some mouse travel- Lots of people didn't realize there even was a right click menu because its a web interface, and they couldn't find some functionality that was only available in the right click menu.Now that being said, we are still debating if it was a good move or not.

Not that I know. As a nice integrated feature, oVirt is rather crappy
at that :) Getting IOPS and bandwidth would, I guess, require you to
install like collectd and send to a graphite or such server, or
simpler, just install e.g. bwm-ng on a host to get a quick snapshot.

Just a thought but, isn´t there any way of getting these numbers from
the storage instead of looking at it from the virtualization? Are there
_a lot_ of other systems connected to it?

Well, that´s not entirely true.

It´s like this: engine-setup versionlocks the packages that it wants to
install and keeps them as they are. Updating them is only possible
through engine-setup.

All of the other packages you update like usual with yum
up(date|grade). So by only running engine-setup, you'll leave a lot of
other packages "behind".

So before, or after engine-setup, you also need to yum up(date|grade),
as well. Sh$t may go wrong if you do, then again, sh$t may go wrong if
you don´t :) Best you can do is ask.

Hey Duck!

Stupid question perhaps but, have I understood it correctly that all of
us are going to have to create new accounts for the new mail-list
system, if we don´t wish to log in using Fedora, GitHub or Google? Or
are the existing local accounts going to be migrated as well?

That's how I interpreted it at least.

Yeah, of course and I think Grzegorz knows that. But for people in the
testing, evaluating stage, making it a virtualized environment gives a
greater flexibility. Easier to test without having to buy any metal.

yes, but it will be applied only after restart. 


 




 
According to the source code, restarting is required during upgrading to 4.1 only if a VM uses random generator device. If it
 doesn’t, a restart is not really required.




 


right, but the VM will still be marked with this "next run configuration" and will be set to have the old compatibility version.

yes, you just change the compatibility version. The VMs which are down will be automatically updated and work with the new cluster, the running ones will be marked with a "triangle"

Re: [ovirt-users] trouble when creating VM snapshots including memory

[Karli Sjöberg]

Den 9 juni 2017 21:40 skrev Matthias Leopold :hi,i'm having trouble creating VM snapshots that include memory in my oVirt 4.1 test environment. when i do this the VM gets paused and shortly (20-30s) afterwards i'm seeing messages in engine.log about both iSCSI storage domains (master storage domain and data storage where VM resides) experiencing high latency. this quickly worsens from the engines view: VM is unresponsive, Host is unresponsive, engine wants to fence the host (impossible because it's the only host in the test cluster). in the end there is an EngineExceptionEngineException: org.ovirt.engine.core.vdsbroker.vdsbroker.VDSNetworkException: VDSGenericException: VDSNetworkException: Message timeout which can be caused by communication issues (Failed with error VDS_NETWORK_ERROR and code 5022)the snapshot fails and is left in an inconsistent state. the situation has to be resolved manually with unlock_entity.sh and maybe lvm commands. this happened twice in exactly the same manner. VM snapshots without memory for this VM are not a problem.VM guest OS is CentOS7 installed from one of the ovirt-image-repository images. it has the oVirt guest agent running.what could be wrong?Seems to me that the snapshot operation, where the host needs to save all of the VM memory chokes the storage pipe, the host becomes "unresponsive" from engine's point of view and all goes up shit creek. How is the hypervisor connected to the storage, in more detail?/Kthis is a test environment where lots of parameters aren't optimal but i never had problems like this before, nothing concerning network latency. iSCSI is on a FreeNAS box. CPU, RAM, ethernet (10GBit for storage) on all hosts involved (engine hosted externally, oVirt Node, storage) should be OK by far.it looks like some obvious configuration botch or performance bottleneck to me. can it be linked to the network roles (management and migration network are on a 1 GBit link)?i'm still new to this, not a lot of KVM experience, too. maybe someone recognizes the culprit...thxmatthias___Users mailing listUsers@ovirt.orghttp://lists.ovirt.org/mailman/listinfo/users___

Of course, once the VM is installed, I can go in and change the RAM to
512 MB and it´ll boot just fine. It´s as you say that it´s just the
installer that absolutely needs it.

That is also an option but I just don´t want to have a dozen images to
update and maintain, I´m lazy:)

FWIW, I created a NIC- and Disk-less Template with the settings I
wanted and pointed to that template in my "Small" Foreman "Compute
profile", so that I could create a VM in oVirt from Foreman with 512 MB
RAM.

PS. CentOS 7 won´t even pxe-boot with any less than 1536 MB any way :(
