Re: [Users] mozilla-xpi for Ubuntu

2013-06-03 Thread Jean-Pierre Pitout



Hi,

I have added it to the below link where I found some other info about 
the spice-xpi. http://www.ovirt.org/Testing/Spice#Testing_Spice_with_Ovirt


I've also had feedback that there is another method:

1. install spice client:
# apt-get install spice-client

2. download spice xpi 
from:https://launchpad.net/~jasonbrooks/+archive/ppa/+packages
# dpkg -i spice-xpi_2.7-0~41~precise1_amd64.deb

The xpi package is compiled for Ubuntu 12.04, but works fine with Ubuntu 12.10 
as well - don't know if it works with Ubuntu 13.04...


I haven't added these steps to the wiki as I haven't tested them yet.

Hello,
I need a working mozilla-xpi for Ubuntu 12.04 (and soon 12.10).
It is strange that an opensource project as ovirt is only working on 
Fedora.


Thanks in advance for any help.

Hi,

I am running Ubuntu 13.04 and got it working using the following steps:

1. Install the spice-client package which gives you /usr/bin/spicec.
2. Extract the libnsISpicec.so file from the latest Fedora (FC19) RPM
3. Placed it in /usr/lib/mozilla/plugins/
4. Restart Firefox

Worked for me!


Nice. Do you mind to add these steps into wiki.ovirt.org ?

2013-06-03 Thread Doron Fediuck
Hi everyone,
On our last visit to Shanghai we discovered there's no
access to YouTube, so oVirt users and developers in China
cannot see the cool video clips we have for oVirt.

To resolve that, we were able to open an account in YouKu
for oVirt, which will host the relevant video clips. I'm
happy to announce oVirt's YouKu page: 

http://i.youku.com/theovirt

Feel free to share with your friends!

Here's how you can help:

- People who do not see their video clips there can
  mail me and I'll upload it to YouKu.

- For new contents please contact me as well so I'll
  upload it to YouKu.

Special thanks to Jimmy and the Intel team, who
helped me with this effort. 

Looking forward to see more video clips,
Doron

Re: [Users] deduplication

Hello Jose,

We also have FreeNAS working in our infraestructure, with about 3 TB and
ZFS. Some of the pools has compression enabled and you can save space with
it. We have this FreeNAS connected to a hypervisor Xen and it works very
well and it's stable and sure. We have nine virtual servers some
wirtualized and other paravirtualized, and some Windows Server machine all
about 2 years in production without any problem. My idea is connect this
infrastructure with oVirt wo be able to have some resources for test VMs in
that. Only wanted to share as another FreeNas success experience.

Juanjo.

 For a primary system; most definitely, yes.

 But for a backup system, that has tons of RAM and SSD's for cache, and you
 have lots of virtual machines that are based off of the template, or are
 very much the same, then you have a real use-case. I´m active at the
 FreeBSD forums where one person reports storing 150TB of data in only 30TB
 of physical disk. The best practice of scrubbing is once a week on
 enterprise systems, though he is only able to do it once a month, because
 that´s how long it takes for a scrub to complete in that system. So you´ve
 got to choose performance or savings, you can´t have both.


 And what about dedup of Netapp?


 Much better implementation, in my opinion. You are able schedule
 dedup-runs to go at night so your user´s performance isn´t impacted, and
 you get the savings. The question is if you value the savings enough to
 take on price-tag that is NetApp. Or just build your own FreeBSD/ZFS server
 with compression enabled and buy in standard HDD's from anywhere... We did;)

 Any way, I think another solution for dedup is FreeNAS using ZFS.


 FreeNAS is just FreeBSD with a fancy web-ui ontop, so it´s neither more or
 less of ZFS than you would have otherwise, And regarding dedup in ZFS; Just
 don´t, it´s not worth it! It´s said that it *may* increase performance
 when you have a very suitable usecase, e.g. everything *exactly* the same
 over and over. What´s not said is that scrubbing and resilvering slows down
 to a snail (from hundreds of MB/s, or GB if your system is large enough,
 down to less than 10), just from dedup. Also deleting snapshots of datasets
 that have(or have had) dedup on can kill the entire system, and when I say
 kill, I mean really fubar. Been there, regretted that... Now, compression
 on the other hand, you get basically for free and gives decent savings, I
 highly recommend that.

  Share a disk containing static data is a good idea, do you know from
 where I can start?

 Everything depends on your needs, design planning. Maybe then sharing
 disk would be better to share via NFS/iscsi. Of course if you have many
 VMs each of them is different you will fail. But if you have mostly
 homogeneous environment you can think about this approach. Sure you have
 to have plan for upgrading base static shared OS data, you have to
 have plan how to install additional software (different destination
 than /usr or /usr/local)... If you already have your own build host
 which builds for you OS packages and you have already your own plan for
 deployment, you have done first

Absolutely agree with you, planning is the best thing to do, but normally 
people want a plug'n'play system with all included, because there is not much 
time to think and planning, and there are many companies that know how to take 
advantage of this people characteristics. 
Any way, I think another solution for dedup is FreeNAS using ZFS. 

/blockquote

FreeNAS is just FreeBSD with a fancy web-ui ontop, so it´s neither more or less 
of ZFS than you would have otherwise, And regarding dedup in ZFS; Just don´t, 
it´s not worth it! It´s said that it may increase performance when you have a 
very suitable usecase, e.g. everything exactly the same over and over. What´s 
not said is that scrubbing and resilvering slows down to a snail (from hundreds 
of MB/s, or GB if your system is large enough, down to less than 10), just from 
dedup. Also deleting snapshots of datasets that have(or have had) dedup on can 
kill the entire system, and when I say kill, I mean really fubar. Been there, 
regretted that... Now, compression on the other hand, you get basically for 
free and gives decent savings, I highly recommend that.

Hi,

Any more info. on this issue?


No not really, you're the only one seeing this, some random idea:

-Is udevd running properly on the box with the problem ?
-Have you tried putting selinux in permissive mode?
-Have you perhaps build some things (ie libusb) from source ?

Regards,

Hans

Re: [Users] Resize storage domain

 Tal,
 
 Thanks for responding, I'll try that sequence. But, what about the vgresize?

There is no such command, only pvresize (which does what you need).

 It will do this by itself? I saw that there are some logical volumes...
 
 Thanks again.

  Hi all!
  
  I have an iscsi domain based on a HP Lefthand cluster. Using HP tool,
  I resized the iscsi volume without problem. On the SPM host, with
  fdisk -l /dev/sdb, I saw the new size, ok.
  
  But now, How do I do ovirt engine see the new size?

 Hi Eduardo,
 
 In case you have more than one host:
 1. Put the domain in maintenance
 2. Manually connect iscsi on the SPM host
 3. Run pvresize on the LUN
 4. Activate the domains
 
 In case you have only 1 host just run pvresize on the disk.
 
 Tal.

Re: [Users] iSCSI and snapshots

2013-06-03 Thread Juan Pablo Lorier
Hi Maor,

The thing is that I trigger the snapshot creation and everything seems
to be ok, but I can't see any new volume of any kind. As the VM runs
from an iscsi lun, it can not use LVM snapshots as there's no spare
space to create any new LMV volume, neither I see any new volume in the
data storage domain (another iscsi lun) so I can't tell for sure that
the snapshot was really created.
Where are the volumes saved if the VM has no spare disks or space?
