Hi,
I'm new to oVirt but I must say I am impressed! I am running it on a HP DL380 with an external SAS chassi. Linux dist is Centos 6.5 and oVirt is 3.4 running all-in-one (for no=
w until we need to have a second host).
Our company (www.vireone.com) deals with system architecture for man=
y telco and media operators and is now setting up a small own datacenter fo= r our internal tests as well as our IT infrastructure.
We are in the process of installing Zentyal for the SMB purposes on = a guest and it would be great to have that guest also serving a fs path dir= ectory with NFS + SMB (which is semi crippled on the host after oVirt insta= llation with version 3 et.c.).
Does anyone have an idea of how I can through oVirt (seen several so= lutions using virsh and kvm) letting my Zentyal Ubuntu guest have access to= a host mount point or if necessary (second best) a seperate partition?
Best regards Niklas
Why not just give the guest a thin provision virtual hard drive and ex=
--=-QO4YC7yJVpEFWdlCUWRr Content-Type: text/plain; charset="UTF-8" Content-Transfer-Encoding: quoted-printable Hello, just add my 2ct: I did a lot of bench marking for our SAN (FC LUN's). I also need file servers for our SMB Clients. I recommend using Direct Attached LUNs for your purpose and attach them to the VMs as VirtIO-SCSI disks. You can even added them as shareable to oVirt if you deploy some kind of SAN file system (we use Quantum's StorNext). Bottom line, the implementation of VirtIO-SCSI is so well done and support in oVirt is great. I cound not see any bottlenecks in the visualization. For the foreseeable future I will not deploy bare metal file Servers again. HTH, On So, 2014-07-13 at 15:47 +0000, Niklas Fondberg wrote: pand it on a demand basis?

Thanks for the advise but this would not suite us I'm afraid. It would = be difficult wrt incremental backups as well as host machine file-routines.
=20 Well, going by Occam's raizor; the simplest answer is usually correct. Ca= n't really tell what you mean by file-routines but backups would be well se= rved by snapshots (can't get more incremental than that) and disaster recov= ery could be as easy as a rsync from inside the guest to a remote machine. =20 The biggest pros here is the ease of being able to setup an export domain= , attach, export the VM, detach domain, and then attach and import to a "re= al" setup when the AIO starts feeling crowded later on. Thinking ahead is n= ever a bad thing, no? =20 /K =20 Thanks for your suggestions! The thing also is that the performance will be very bad if we have the 25= TB SAS array shared for our purposes (lots of media streaming) using a virt= ual disk. What I am after (after more reading) is support for virtio-9p-pci (http:/= /www.linux-kvm.org/page/9p_virtio) using oVirt. Alternative is the Direct L= UN hook (http://www.ovirt.org/VDSM-Hooks/directlun, if I can figure out how= to work with hooks...) Any chance anybody has an answer for these questions? =20 _______________________________________________ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users
