Hi All,

I have created a VM with 60GB of disk space.
I have started I/O inside the VM, after sometime when the disk was 
4GB full,

I took a snapshot of the disk from UI.

I/O kept continuing and the new image file ( overlay file ) was 15GB in
size.

Now I deleted the snapshot.
I think this would initiate block-merges.
During this time, my I/O was were slower, till the snapshot delete is
completed.

Its not very slow, but slow.
Is this a known behavior ?


Hi Satheesaran,

It sounds like this was a live merge, ie snapshot removal while the VM 
was running.  This is currently implemented as a block commit, where 
data from the snapshot (your 15GB overlay, in this case) is merged down.


For snapshot deletion to complete, this means that your concurrent I/O 
and the data already in the overlay have to be written into the 
next-lower image.  So in short, yes, depending on the storage system 
backing your VM, I/O may slow down a bit until completion.


HTH,
Greg

Greg,

Thanks for that information.
I too expected it, but really wanted to confirm the behavior.

[ovirt-users] During Hosted Engine Deployment. CPU Type not listed as compatible. No selection to choose from.

[Langley, Robert]

Host is a Dell PowerEdge 2950 with an Intel Xeon 5160 (Woodcrest) processor.
I'm stuck at the prompt, "Please specify the CPU type to be used by the VM []" 
during the deployment.
There is nothing to select. No compatible CPU type is shown.
The server is from 2008 and I'm needing to use these older servers to get 
started, before I can bring in the newer ones that are busy hosting VMs.
The other Dell PE 2950 is from 2007 and I was able to bring up the engine on 
that one. It is a Conroe CPU. I won't get into my mistake with that deployment. 
I'm working on recovering from that one.
I wanted to post about this, because I was trying to add this one (2008) as an 
additional host and it wouldn't add, due to the processor.
So, one question (in addition to the problem above) is whether or not I can use 
two hosts with two different processors for the hosted engine?
Thanks

Re: [ovirt-users] Adding another host to my cluster

[Gervais de Montbrun]

Roy,

Thank you so much for asking for the logs on the engine. The serial.txt bein 
blank was my issue. I found a solution in the following thread online here: 
http://lists.ovirt.org/pipermail/users/2014-November/028870.html
I did the exact same thing that Dinuwan did to solve his issue back in 2014 and 
was able to enrol my new server and install the hosted-engine just fine on it.

I am not certain what caused serial.txt to be empty and am will to share logs 
to anyone from the oVirt team who might want to see them. For my purposes, I'm 
considering this issue solved.

Thanks to everyone who offered advice and suggestions.

Cheers,
Gervais

Re: [ovirt-users] Adding another host to my cluster

Hi Roy,

I've added /var/log/ovirt-engine/engine.log to my DropBox: 
https://www.dropbox.com/sh/21lkl6ao3hv2r85/AADDMCK4Dp7UYgs5P6dMQxHKa/vdsm?dl=0 


When I look in the engine.log, I see the error "unable to load number from 
serial.txt"
I did a find for serial.txt and the only file that comes up is: 
/etc/pki/ovirt-engine/serial.txt 
(Makes sense that this is the file it wants to read)
When I open /etc/pki/ovirt-engine/serial.txt, it is an empty file. 
[root@cultivar ovirt-engine]# cat /etc/pki/ovirt-engine/serial.txt
[root@cultivar ovirt-engine]# 

What should be in serial.txt?

I don't understand where to find the other log that you mention in your email 
below. I don't see any paths listed in the UI when I click on the failed event 
for certificate enrollment.

While I cannot answer your actual question as I don't know enough about the 
internal implementation of how oVirt interacts with gluster. I just want to 
point out major difference between oVirt and VMWare. In oVirt storage domains 
are attached to data centers, not hosts. So there is no does the disk move 
from host1 to host2. The disk is on the storage domain and host1 and host2 and 
every other host in the data center has access to the storage domain.

[ovirt-users] oVirt Node 3.6

[Anantha Raghava]

Hi,

I attempted to download the oVirt Node 3.6 from 
http://resources.ovirt.org/pub/ovirt-3.6-snapshot/iso/ovirt-node-iso/ 
and I also find there is another ovirt-node-ng. Which one should we 
download.


I downloaded the one at 
http://resources.ovirt.org/pub/ovirt-3.6-snapshot/iso/ovirt-node-iso/, 
but this iso file seems to have an issue. Although it boots the server 
properly at around 66% into installation, the installer throws up an 
error - I/O error, file not found or some thing of this sort. 
Installation doesn't go forward at all. We have to power off the server, 
reboot with CentOS DVD install using yum local install command.


Are these files proper? Which one should we use?

[ovirt-users] disk order in vm and disk order in export

[Fabrice Bacchella]

I have a VM with the following disks (in the ordrer return by a get query):
 

...
vm_sys
17179869184 <- 16GiB
virtio_scsi
true
image



vm_data
virtio_scsi
false


1099511627776 <- 1 TiB.
0


lun


So the first one is a 16 GiB virtual disk, the second one a 1 iTB direct access 
LUN that will contains data.

But once booterd, I see:
lsblk   
NAMEMAJ:MIN RM   SIZE RO TYPE MOUNTPOINT
sda   8:00 1T  0 disk 
...
sdb   8:16   016G  0 disk 
...

and :
ls -l /dev/disk/by-*/*
...
lrwxrwxrwx. 1 root root  9 May 16 09:03 
/dev/disk/by-path/pci-:00:04.0-scsi-0:0:0:0 -> ../../sda
lrwxrwxrwx. 1 root root  9 May 16 09:03 
/dev/disk/by-path/pci-:00:04.0-scsi-0:0:0:1 -> ../../sdb

So the first disk sda is the second non bootable disk.
What set the disk order associated to a VM ? Is there a way to enforce that the 
first disk is really the first disk ?___

[ovirt-users] How to migrate un-migratable VMs?

[Nicolas Ecarnot]

Hi,

Some VMs are doing high guest-memory writes (mainly files and mail 
servers, but not only), so migrations are reproductively failing.

I found some info here :
https://bugzilla.redhat.com/show_bug.cgi?id=919201
that confirm what I was fearing.

This BZ is aging from dinosaurs times, so I was wondering now we're in 
the 3.6.x age and 4.x coming, are there advices one may give to migrate 
those verbose VMs?


I guess increasing the allowed page memory is not a correct answer as it 
will fill as before.


Any thoughts?

[ovirt-users] USB

[Brett I. Holcomb]

How do I get a VM to see USB devices?  If I understand it correctly I
have to go to Edit VM -> Console and enable USB native.  I have the
console options set to use usb.  However, I'm finding conflicting
information.  Supposedly libvirt will allow sharing of a USB device
over a network but to start with I'd be happy just being able to
connect a usb device to the host and having it detected.  I have some
programmable devices I'd like to program in Linux using my VM.

Has anyone uses usbip and if so how well does  it work?

[ovirt-users] oVirt & gluster - which copy is written to?

[Bill Bill]

Hello,

Let’s say I have a 5 node converged cluster of oVirt & glusterFS with a replica 
count of “3”.

Host1 - replica
Host2 - replica
Host3 - replica
Host4
Host5

If I spin a VM up on Host1 – does the first replica get created local to that 
server?

In the event I move the VM to another host, does the replica of the disk follow 
the VM so essentially it’s writing to a local copy first or does it “always” 
write across the network.

For example, with VMware, the disk will follow the VM to the hypervisor you 
move it to so that the writes are essentially “local”.

I have not been able to find anything on the internet or in the documentation 
that specifies how this process works. Ideally, you wouldn’t want a VM residing 
on Host1 that accesses its disk on Host3. Multiple that by hundreds of VM’s and 
it would create a ton of unnecessary network congestion.

As for the original BSOD, the problem there was trying to load Win8
vioscsi.sys on Win7 and should be fixed by pointing Windows to the
Win7 subdirectory like you wrote.

Relevant bugs:

https://bugzilla.redhat.com/show_bug.cgi?id=1296633 (target OS version mismatch)

No worries. I forgot to mention that this will be fixed in a future
driver release, either by dual-signing the binaries with both SHA-1
and SHA-2 or only SHA-1. Requiring the Windows hotfix is a workaround
until then.

It is the same issue though, I have checked the timestamp in your BSOD
screenshot. The driver running on the system at the time of crash was
a build targeted at Win8 or newer.

Can you feed only the Win7 subset of the ISO to WDS? Sorry, I am not
familiar with WDS enough to be more helpful.

The problem with all the virtio-win releases so far is that the
drivers don't declare the minimum Windows version they support. So
Windows (or in this case WDS?) is free to choose any of them, usually
going after the highest version which tends to be the Win8 variety.
This will also be fixed soon.

What does it say when you click "Show details"?
