I don't think it's serious, it can easily be changed via a hook, there's also 
an RFE somehwere in queue for this to be configurable directly in UI (not much 
work, 3.5 perhaps)
and since inside the guest you are not aware of migrations you can't really 
"trust" that value anyway

well, yes. But in addition in /etc/vdsm/vdsm.id you can define your very own 
host UUID
but by default yes, after enough runs….

Hi Neil,
hm, other than noise I don't really see any failures in migration.
Can you attach both src and dst vdsm log with a hint which VM and at what time 
approx it failed for you?
There are errors for one volume reoccuring all the time, but that doesn't look 
related to the migration

 Hi guys,
 
 Apologies for the late reply.
 
 The VM (Tux) was created about 2 years ago, it was converted from a
 physical machine using Clonezilla. It's been migrated a number of
 times in the past, only now when trying to move it off node03 is it
 giving this error.
 
 I've looked for any attached images/cd's and found none unfortunately.
 
 Thank you so much for your assistance so far.
 
 Regards.
 
 Neil Wilson.

good it's working for you
I was also checking the internal error and it's

Hi,
well, as a first step, attach logs:-)
If possible from engine, source vdsm and destination vdsm, along with the VM 
name in question and let's see what's going on….

IE11 doesn't really work as of now.
Try some more reasonable browser, IE10 would be also fine.

activex setup requires some manual work as mentione at 
How_to_Connect_to_SPICE_Console_With_Portal wiki
native invocation (that file to download you got) is easier, just associate 
with recent remote viewer and it should open 
it works on Windows, Linux and OSX (needs 
https://github.com/brianwcook/launchvv in addition)

we extend before run out of space so it should not really happen in real life, 
not in reasonable setups.
unlike the out of space scenario where there's little we can do, just pause.

the threshold for growing the space can be change…or simply use preallocated 
disks if the performance is so bad and VM demands so high.

yeah, I guess it should go under VM's guest_info (there's guest's IP and FQDN

setting the ticket is a VM's action "ticket"
after that you can spawn your client and connect to the desired host/port you 
get from VM display's address, secureport

minor note: the secure port is the one to be used as by default the host will

there are two steps
you get the password via ticket action (which enables/opens the connection for 
those 120s window)
you get the display details from VM's properties (host, port)
and then you can connect. 

for novnc you'd need to use websocket proxy in addition so you need to get the 
proxy address from engine-config

right, so what do you miss?
perhaps the websocket proxy address, I don't think it's exposed via REST:/ 
Don't know. Maybe use a fixed one in your environment is good enough?
other than that you have everything, no?

Thos is way beyond graphics issues. You have something wrong with the basic 
setup. Storage connection?
Can all hosts see the engine and vice versa? Any manual firewall tweaks?

Well, whatever is the reason the symptoms you see suggests something is either 
crashing (vdsm on the host) or is unreachable or misconfigured now. 
Depends what you did...:)
Might be easier to start from scratch if unsure...

Yes, that's fine, this is the default deployment/installation. You sure you 
opened firewall for websocket proxy? Is is running? Engine-config's 
WebsocketProxy(or similar) parameter points to the right thing?

It's for both noVNC and SPICE-HTML5 client
Not for virt-viewer or custom native vnc clients
"Spice proxy" would be for similar network layout but native spice client 
(remote-viewer or firefox/IE plugin)
I may have missed that info earlier, are you trying to use browser clients? 
Those need the websocket translation. Or regular/stable way via standalone 
client(that's still the predefined default)

[Users] multiple storage domains

[Michal Skrivanek]

Hey,
I was trying to play with multiple storage domain during the 3.4 test day and 
even though it took me ages to set storage up correctly, the feature itself 
seems to be working just fine. Much easier to select what kind of storage I 
want to use…just Shared vs Local storage pool. VM could use volumes from 
different domains and I didn't have to worry about the right type (other than 
local vs shared, obviously:)

Thanks,
michal

Hi,

your log doesn't contain the relevant part, there's no command logged, other 
than
"Message: VM wcsmail01 is down. Exit message: User shut down"
which means the guest was shut down from inside of the OS

how did you trigger the reboot/shutdown?

Thanks,
michal

ok, makes sense there's nothing in the log

what doesn't make sense is the behavior:) It should simply reboot, there's 
nothing oVirt is doing in this case…could it be your OS is configured(or has 
decided) to shutdown instead?

that is weird. Any special/non-default setting?
do you have libvirt/qemu logs? VDSM doesn't say much other than a clean 
user-initiated shutdown happened.
is ACPI enabled in the guest (unless you manually changed config it always is)
any logs from the guest?

mapping to Other seems to be fine
If you delete it "0" well, bad luck;)
It also means that with this mapping if you open a running VM and try to save 
it it may likely fail as it tries to update various fields. Well, bad luck 
again.

I'd address this in bug https://bugzilla.redhat.com/show_bug.cgi?id=1046809

which, as I learned last week, is not entirely correct. Pure libvirt VM seems 
to work fine…so it must be somewhere something in oVirt:(
looking into it
but just for future reference we want it to work:)

since it's a proxy as well I'd recommend to use it instead of squid, not in 
addition. By default it's installed on the engine host but it can be deployed 
anywhere else.

Well, this is the default deployment on engine. The engine host is the proxy. 
If that's what you need there is no additional configuration needed. Just say 
yes to websocket proxy during installation and import ca.crt to your browser

Only if you want to run the proxy elsewhere you need to update the below 
parameters accordingly

indeed. The scope of the feature was cut down significantly. No customizations 
other than via vdsm.conf. We hope we'll get the original promises in 3.5:)
The default 60 seconds delay time is for shutdown as well. The future 
customizations are to remove it.

it seems only the Windows version of virt-viewer supports the mapping. We'll 
grey it out for Linux clients then (or try to push the change to Linux versions 
as well, whichever can be done first)

the vdsm.conf has a description for each parameter…just search for all

we do want to expose some/most/all of them in UI/REST eventually, the 
"migration downtime" setting is there now in 3.4, but others are missing

 My migration network is IPoIB 10GBit. During our tests only one VM
 was migrated.  Bandwidth cap or number of concurrent VMs has not
 been changed after default install.
 
 Is migration_max_bandwidth in /etc/vdsm/vdsm.conf still the right place?

not sharing, but overcommit yes. 
if it really needs more RAM than the host has then it's going to swap…well, you 
may try to use network swap I suppose
performance is not going to be great in any case, obviously.

there were/are two issues.
- one in vdsm reporting it which has been merged recently
- then this engine not actually updating the field. This is a regression, 
though it must have happened quite some time ago…may be after 
https://bugzilla.redhat.com/show_bug.cgi?id=967861
A similar solution is supposed to be there for Windows VMs but if I'm not 
mistaken it's not in place yet. I'll check that

In 3.4 it's there finally, I forgot we changed the dialog for "vminit" feature.
So the TZ dropdown box in General tab should set the time for the next run. 
It's supposed to be changeable for Windows OSs (Linux is always 0). It works in 
UI but apparently the backend code is not changing the utc_diff value. So that 
one we need to fix.
And the updates from vdsm side are not reflected in DB if I understand what the 
bug says…the code looks alright though, so need to verify

Thansk,
michal

The Console Downloads page has all the info to get it work, did you check it 
out? (linked from main landing page, display options, user portal...so you

Strange. I think it's in 0.5.6.

Not when you don't trust the cert authority. Unfortunately. That's why we added 
the page to such a prominent place:)

Yep. For some reason only remote-viewer works. No idea why

Remote-viewer should work the same for VNC. For cclient of choice yes, your 
script is the one to use

alternative is to use the native client or plugin:)
you have 3 choices, unfortunately each needs some action/installation.
But hopefully one out of three should work for everyone

can you do a live VM snapshot at all? If not then the QEMU you're running is 
not supporting it

the recent enough virt-viewer should work on Windows…if you're in fact talking 
about a client downloaded from http://virt-manager.org/download/ it should work…

for NAT vs non-NAT access ….for exactly that reason there is the "Enable SPICE 
Proxy" checkbox in Console Options dialog for each user, so you can check it 
when connecting from outside and uncheck from local net…

 Yes I am sure its related to the upgrade.

only upgrade, not a specific VM run? In other words it doesn't check the BIOS 
serial number since that's different on each hypervisor.

 
 In the application log of the VM we can see  "hardware has changed from
 previous boot" and also we have a licensing system on another host that
 got in a stucked state because of the same reason - "hardware has
 changed from previous boot".

in addition to stable PCI addresses, new QEMU/KVM release sometimes change the 
system hardware - emulated machine mode.
or if it is really subtle, it can also be triggered by new devices (e.g. 
balloon, virtio-console (used to be in 3.0, removed in 3.1, optional in 3.3)) 
or simple upgrade of virtio drivers

anyway, so what changes in devices you can see after upgrade?

nope. just the API way.
I don't find the solution of someone going in manually entering the pwd on some 
command line as something not really ideal. The .vv should be associated with a 
script or remote-viewer and then 120s should always be enough to launch it

yes, if it is supported now the oVirt ticketing would need to be changed or

with storage offloading it's probably not going to be significant, however 
today it likely is.
Nir, why would not using migration network make it better? Won't we have the 
same problem as before without migration network at all, i.e. choking the 
management channel?
Should we maybe consider a dedicated "storage" network?

well, sort of both. We keep the QEMU/libvirt  default which is to honor 
client's request.
Which is in case of novnc by default "shared", other common clients like 
vncviewer default to "disconnect"

I wonder if anyone is using the shared behavior or we should disallow it. Or 
make it optional, which is nice but as always comes with a price of development 
time.

well, you saturate one or the other…still from the functional perspective it's 
better to not choke the management…so either use the migration network (and the 
migrations will compete with disk moves) or a separate network.
I'd be tempted to say that typically having too many different networks might 
be an overkill and difficult to set up/maintain

Yes. We can now remove quite a few limitations specific to the blank template. 
Thinking of renaming it to "default" and allow editing and versioning it. 
You can't delete it at the moment though

Hi,

all 14 of them?

Might be. Does it disappear when you disable quota?:)

seems a destination creation issue. Please reproduce with one VM and get the 
logs from both source and destination host from that time.

Internally it will need to do a snapshot as well, so the flow you can write now 
won't be much different, just more api calls

likely
the guest's HW clock should be now set to the offset of the selected TZ. For 
default Linux installs this should be UTC (I think still you can't select 
anything else), for Windows this should be the desired time zone.
Not sure how it handles DST but at least it should be consistently coming up 
with the same time:)

michal

note so far in 3.4/3.5 still the only thing it brings you is the Backup API 
feature - quiesce of drives during taking of the snapshot.
For most of other uses you don't actually need it and you can --nodeps it...

Hi,
this is more for the KVM folks I suppose…can you get the qemu process cmdline

as said before, it's not safe hence we (try to) not migrate them.
They only get paused when they actually access the storage which may not be 
always the case. I.e. the storage connection is severed, host deemed 
NonOperational and VMs are getting migrated from it, then some of them will 
succeed if they didn't access that "bad" storage … the paused VMs will remain 
(mostly, it can still happen that they appear paused migrated on other host 
when the disk access occurs only at the last stage of migration)


so in other words, if you want to migrate the VMs without interruption it's not 
sometimes possible
if you are fine with the VMs restarted in short time on other host then power 
management/fencing will help here

you need to edit the VM and change it's display, pretty much the same way as

It's a bit more complicated than that….there's no XML stored in the backend. 
You'd be better off applying the patch over and compile yourself:)
The supported way of how to amend the libvirt XML is via VDSM hooks. You need 
to intercept the created XML and add whatever is needed, see 
http://www.ovirt.org/VDSM-Hooks, some of the examples can be used as a base for 
what you're trying to do...

 the dropdown field is editable so one can enter any custom domain 
then it gets replaced in the system's sysprep template. 

the same goes for user credentials - tehre's the Alternate Credentials 
checkbox…does it not work?

BTW note in 3.4 you would be able to use a custom sysprep file (with existing 
variables substitution)

you're not supposed to need a hook under normal circumstances, when the 
functionality is useful enough it should be built into vdsm natively…well, 
that's in progress for this one for 3.4.1:)

yes, the cluster needs to remain.
We're finally taking some steps to be able to remove/replace a Blank 
template…nothing final yet.

there you should see some specific error…I guess. If this is really related to 
that removal, there should be something in the log. I'm not aware of any change 
in the API itself…

it's not about every possible use case, it's about keeping the code working. 
Letting hooks go wild and unmaintained is not a good idea…
There were discussions on mailing list about having a nice interface in UI for 
hooks  but as far as I remember it was always turned down
Though I personally would welcome at least a monitoring of deployed hooks 
somewhere in the UI…

well, there are things which need to be verified first. Only detach works for 
sysprep floppy. It would probably work for CD…but they can be bootable so need 
to check the impact.
changing bootorder only - we didn't yet check if we can even do that

you have to differentiate - if only the VMs would be paused, yes, you can do 
anything (also change the err reporting policy to not pause the VM)
but if the host becomes non-operational then it simply doesn't work, vdsm got 
stuck somewhere (often in get blk device stats)
proper power management config should fence it

I'm not entirely sure that the after_vm_pause() hook gets invoked in this case. 
It was not intended for involuntary pause…but give it a try!:)
otherwise ….well, you can always do a periodic query…not very effective though

what kind of storage you're using? if it is block-based it zeroes out the data

Hi,

you don't need any networking in the guest for console access

are you opening the console via that .vv file? Do you have a recent-enough 
virt-viewer? Check out http://www.ovirt.org/Console_Client_Resources

Re: [ovirt-users] VMs get hang

only the last one:) the management node is not involved in performance of 
individual VM host nodes nor in the console communication

it may be network between the clients and hosts. Then worth checking the VM's 
guest load, then host's overall load (that would be that slow storage)

if you plan to overcommit then go with thin. The drawback is that if you of 
course hit the physical limit the VMs will run out of space...
if you plan to allocate 500GB each, consume all of it, never plan to grow then 
go with the "clone"….yes, it's going to take time to write all that stuff. With 
"thin" you need to do the same amount of writes, but gradually over time while 
you're allocating it it

hope it helps

it's going to work, it just may get a longer time to bring them up when you

there's no defined max….it just gets sluggish depending on your setup/layout

yes. It got side-tracked by implementing the detection whether it's there or 
not, that is now implemented.
we still want to track building it ourselves…I'm not sure how far we

you can try GUI Import VM via libvirt, unless you use some exotic

that’s possible as well, disk by disk.

Hi Joseph,
ballooning is unrelated to the memory hot plug. You need ballooning for memory 
overcommit to reclaim the guest’s memory back to host/other VMs. If that is 
what you want to do the just enable ballooning and use 16GB memory size

hotplugging is user action, on demand. If you want to have complete control 
over the guest memory size you can use hotplugging without balloon.
It’s somewhat overlapping, ballooning is more flexible(can inflate and deflate 
based on host memory pressure), on the other hand requires guest cooperation 
and some time to settle on the right value.

can you run that as a “vdsm” user? You need to exchange keys for “vdsm” (note 
it has disabled login, so you need to use "runuser" or something)

You don’t have to decide, you can keep the default 4x.
For CPUs it is not currently needed and is set according to engine-config 
maximum supported by qemu-kvm - 288 in 4.1

Why not reserving regular hugepages for VMs on boot? then you can use
it with vdsm hook for that Oracle VM. It improves VM performance in
general, the only drawback is less flexibility since that memory can't
be used by others unless they specifically ask for  hugepages.
Also, I suppose you disable KSM, and I'm not sure about ballooning,
unless you need it I'd disable it too.

The hook is being improved right now in master, but it should be
usable in stable too.

You _have_ to do that manually, oVirt won’t restart them for you, it will just 
keep nagging with the “pending change” triangle icon. This is so you can do 
that whenever it is convenient for that particular VM
A bit more is going to change for that VM - the emulated hardware is being 
changed, as well as behavior of oVirt features leveraging them (mostly the new 
features requiring some QEMU functionality, like hot plugging, higher number of 
vCPUs and such)

Sorry for using the confusing term - A guest-side reboot is not sufficient, it 
needs to be a power cycle from guest POV, so shut down and power on in oVirt
