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 now =
until we need to have a second host).
Our company (www.vireone.com) deals with system architecture for many =
telco and media operators and is now setting up a small own datacenter for = 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 direc= tory with NFS + SMB (which is semi crippled on the host after oVirt install= ation with version 3 et.c.).
Does anyone have an idea of how I can through oVirt (seen several solu= tions 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 expa= nd it on a demand basis?
/K
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.
Well, going by Occam's raizor; the simplest answer is usually correct. Can'= t really tell what you mean by file-routines but backups would be well serv= ed by snapshots (can't get more incremental than that) and disaster recover= y could be as easy as a rsync from inside the guest to a remote machine. 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 "real= " setup when the AIO starts feeling crowded later on. Thinking ahead is nev= er a bad thing, no? /K Thanks for your suggestions! The thing also is that the performance will be very bad if we have the 25TB= SAS array shared for our purposes (lots of media streaming) using a virtua= l disk. What I am after (after more reading) is support for virtio-9p-pci (http://w= ww.linux-kvm.org/page/9p_virtio) using oVirt. Alternative is the Direct LUN= hook (http://www.ovirt.org/VDSM-Hooks/directlun, if I can figure out how t= o work with hooks...) Any chance anybody has an answer for these questions? --_000_CFE875E3219BBniklasvireonecom_ Content-Type: text/html; charset="iso-8859-1" Content-ID: <5A76E9D251C9A743BC133AC39E2E7684@eurprd04.prod.outlook.com> Content-Transfer-Encoding: quoted-printable <html> <head> <meta http-equiv=3D"Content-Type" content=3D"text/html; charset=3Diso-8859-= 1"> </head> <body style=3D"word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-lin= e-break: after-white-space; color: rgb(0, 0, 0); font-size: 14px; font-fami= ly: Calibri, sans-serif;"> <div><br> </div> <div><br> </div> <span id=3D"OLK_SRC_BODY_SECTION"> <div style=3D"font-family:Calibri; font-size:11pt; text-align:left; color:b= lack; BORDER-BOTTOM: medium none; BORDER-LEFT: medium none; PADDING-BOTTOM:= 0in; PADDING-LEFT: 0in; PADDING-RIGHT: 0in; BORDER-TOP: #b5c4df 1pt solid;= BORDER-RIGHT: medium none; PADDING-TOP: 3pt"> <span style=3D"font-weight:bold">From: </span>Karli Sj=F6berg <<a href= =3D"mailto:Karli.Sjoberg@slu.se">Karli.Sjoberg@slu.se</a>><br> <span style=3D"font-weight:bold">Date: </span>Sunday 13 July 2014 14:51<br> <span style=3D"font-weight:bold">To: </span>Niklas Fondberg <<a href=3D"= mailto:niklas@vireone.com">niklas@vireone.com</a>><br> <span style=3D"font-weight:bold">Cc: </span>"<a href=3D"mailto:users@o= virt.org">users@ovirt.org</a>" <<a href=3D"mailto:users@ovirt.org">= users@ovirt.org</a>>, Karli Sj=F6berg <<a href=3D"mailto:Karli.Sjober= g@slu.se">Karli.Sjoberg@slu.se</a>><br> <span style=3D"font-weight:bold">Subject: </span>Re: [ovirt-users] fileserv= er as a guest oVirt<br> </div> <div><br> </div> <blockquote id=3D"MAC_OUTLOOK_ATTRIBUTION_BLOCKQUOTE" style=3D"BORDER-LEFT:= #b5c4df 5 solid; PADDING:0 0 0 5; MARGIN:0 0 0 5;"> <div> <div> <p dir=3D"ltr"><br> Den 12 jul 2014 22:49 skrev Niklas Fondberg <<a href=3D"mailto:niklas@vi= reone.com">niklas@vireone.com</a>>:<br> ><br> ><br> ><br> > On 12 jul 2014, at 16:57, "Karli Sj=F6berg" <<a href=3D"m= ailto:Karli.Sjoberg@slu.se">Karli.Sjoberg@slu.se</a>> wrote:<br> ><br> >><br> >> Den 12 jul 2014 15:45 skrev Niklas Fondberg <<a href=3D"mailto:= niklas@vireone.com">niklas@vireone.com</a>>:<br> >> ><br> >> > Hi,<br> >> ><br> >> > I’m new to oVirt but I must say I am impressed! <b= r> >> > I am running it on a HP DL380 with an external SAS chassi.<br=
