Hi! 

I have tested also with last version of Ovirt 4.4, and I see that writing
speed in 4 times more then with fuse. I think this is important reason to
support snapshots with Libgfapi.

2020-02-02 Thread Alexandr Mikhailov
Yes. The problem with permission. But not with permissoin on export directory. 
Two ways to
resolve this:
1) Make 777 permission on directory - dont right solution.
2) anonuid=36,anongid=36 in export - this right solution, very strange that 
this is not in
any documentation, but very important!
I has right permission on my export directory, but this is not working before i 
mke 777
chmod. After i chande parameters in exports file i return chmod to 755 and all 
working
fine now!
Thank you and all very much.

I don't know about 4.2, but in 4.1 and 4.0 there is a right-click
context menu that gives you access to the Power Off feature.  If that
doesn't work (ISTR disucssion about removing that context menu), then
there must be a different way to access it now.



In 4.2 User portal was replaced with new VM portal. There is no

From admin portal I can poweroff VM.

When I was creating the particular VM in 4.1 it was working as expected.

The hostdev from before the upgrades are still present. I tried to
remove them and got an NPE (see below).

As a workaround, is the old hostusb[1] method I know back from 3.x still 
working in the 4.x
line?

I don't think you need care about it, because its real value calculates
via internal algorithms. Generally it depends on your workload. if you
have VM's that do a lot of random writes try to set recsize to equal or
greater value of guest file system block size.

Did you read this white paper? It might help you.

When VM did not start after upgrade I did many different steps including

 Subject: [ovirt-users] CPU Threads Help!!!



 Hi, Guys Recently I am investigating the Optimization Policy in
 Cluster and try to use “ CPU Threads ”.

 As the manual of description:

 

 For example, a 24-core

 system with 2 threads per core (48

 threads total) can run virtual machines with

 up to 48 cores each

 



 My host CPU is

 i3-2120 CPU (2 cores 4 threads)



 So I think the expect result case is :

 1. If the “ Count Threads As Cores ” disable , we can’t run virtual
 vm with above 2 vCPU

 2. If the “ Count Threads As Cores ” enable , we can’t run virtual vm
 with above 4 vCPU



 Now the problem is about result case 1:

 1. When I set “ Count Threads As Cores ” disable , I still can run
 virtual vm with 4 vCPU

 Can anyone help me to explain it ???

 Like Artyom mentioned, it best to see your lscpu output but my guess
 is that the 4 threads is actually 2 per core.
  And there are 2 core and 2 sockets. this means 4 cpus without hyper
 threading and 8 with.

 BTW the Host General subtab on the webadmin should output all this
 info as well. Check it out.

According to ARK Intel Core i3-2120 cannot be used in dual-socket
configurations.

 I haven´t tested anything since last time but good to know someone doing
 something:) I can imagine the guest agent would need some tweeking to
 get it running as well:

 http://lists.freebsd.org/pipermail/freebsd-emulation/2013-April/010569.html
 The VirtIO spec is written with mostly Linux in mind and usually takes
 varying amounts of extra effort to adapt to FreeBSD.


I have successfully build and run guest agent on FreeBSD-Current. It
provides a few information (for example fqdn and logged users) into
admin portal, but all other requires rewriting GuestAgentLinux2.py or
implementing it as separate module. I have no experience in python and
programming itself, but implementing some simple features may be quiet
easy. Can anyone help with it?

Re: [ovirt-users] engine-reports portal and cpu cores

2015-05-13 Thread Alexandr Krivulya
Ок, I understand it. But in admin portal on hosts detail tab I see for
example 32 logical cores vs 16 in reports because of Hyper-Threading
enabled. All VM's on this host consumes 26 vCores. Does it
overallocation? According to report - yes, but actually I think not.

Can you clarify?

13.05.2015 10:32, Shirly Radco пишет:
 H Alexandr,

 The vCores are the logical cpu cores, 
 and if you has more vCores than Host Cores it means that you have over 
 allocation for the hosts.
 So, if on a specific vm one of the cores will be on 100% usage than all the 
 vms using this core will show 100% as well.

 Is it necessary to export VMs that are straight libvirt/KVM (raw) images

 I have a working oVirt 3.5 lab environment up  I’d like to try and bring in 
 some of my existing VMs from my straight KVM/libvirt setup.  Those VMs are in 
 raw image format.

 I *think* I need to export the VMs (using virt-v2v) from the KVM hosts to an 
 export domain, then import those VM images into oVirt (using oVirt admin 
 GUI).  Is that correct, or is it simpler than that?

Yes, you are absolutely right. We moved all our infrastructure from pure
KVM (VM disks inside LVM) to oVirt in this way, except of FreeBSD VM's
that we moved via zfs send/recv.

 3. Is there any way to restore the backup (after point 2) ??

 Can anyone on this list shed a light on when RHEV might be a better

IMHO, great plus for RHEV is vendor support (it's related not only to
RedHat products). If you can spend days in troubleshooting - stay with
ovirt. But sometimes it is not acceptable for business. I don't see any

 Now I have two questions:

 1. If setup fresh ovirt installation how can I attach an existing
 gluster storage and import disks? Are
 http://www.ovirt.org/Features/Import_an_existing_Storage_Domain and
 http://www.ovirt.org/Features/Domain_Scan already implemented in 3.3.2?
 or
 2. May be I can move these disk images into a new SD?

 we're working on this, but for now you can only attach a clean SD. you
 can later move to it the disks and register them via the domain scan

Can anyone tell me how can I use domain scan to register disks? I cannot
find any relevant info.

 the right way to do this would be to restore it not via engine, then
 use the rest api to edit the storage domain connection (mount) in
 the
 engine.

 alisa/derez - any reason we don't support edit connection for gluster sd?

Three steps to solve my issue on node B:

1. install qemu-kvm-0.12.1.2-2.415.el6_5.3
2. set correct permissions on /var/lib/libvirtd/qemu
3. add qemu user to group kvm

Hi!

I want to build small gluster storage with two nodes, 2x3Tb HDD in
md-mirror on each. What parameters should I use in mkfs.xfs for optimal
perfomance with ovirt? Should I use -s size=4k or something else?

 Hi guys,

 Does anyone have any successful upgrades from 3.1 to 3.2 using Centos
 6.3 and the Dreyou repos?

 I'm using ovirt 3.1 on our own production systems and would like to
 know the recommended upgrade methods/paths. I don't see much in the
 way of upgrade paths for any distributions for that matter.

 I've done quite a lot of googling and can't find much, also checked on
 the ovirt website for any possible guides or methods without much
 success.

 Thanks in advance.

 Regards.

[Users] local usb device

Hello!

Can anyone tell me how can I redirect into VM local usb device plugged
into ovirt node's usb port? Currently with libvirt and kvm it works this
way:

   hostdev mode='subsystem' type='usb' managed='yes'
  source
address bus='1' device='3'/
  /source
/hostdev

I do not have any X11 environment on my node (Centos 6.3) and I cannot
use spice client.
