What You Need to Know About XenServer
-
@wirestyle22 You need to rescan the SR to find freshly downloaded ISOs.
edit: local share are not officially supported by Citrix, so you can do it but if you can use a NFS/SMB share somewhere, that's even better

@BRRABill I did run into complications while trying to create an ISO Library. It seems pretty unintuitive to me.
mkdir -p /var/opt/xen/ISO_Libxe sr-create name-label=LocalISO type=iso device-config:location=/var/opt/xen/ISO_Store device-config:legacy_mode=true content-type=isocd /var/opt/xen/ISO_LibI then ran into issues locating the actual link so I could
wgetI found this one eventually:
http://care.dlservice.microsoft.com/download/7/5/E/75EC4E54-5B02-42D6-8879-D8D3A25FBEF7/7601.17514.101119-1850_x64fre_server_eval_en-us-GRMSXEVAL_EN_DVD.iso?lcid=1033&cprod=WinSvr2I didn't see any failure notifications. However, there was also no ISO's listed in the library.
I ran
df -hto find disk usage and it didn't have enough space so I switched to my 8 TB GPT Partition.cd /var/run/sr-mount/etc etc etc code/Then I went through the process of creating another directory. I moved it to the new ISO_Lib folder and ran this:
xe sr-create name-label=ISO_Lib type=iso device-config:location=/var/run/sr-mount/etc etc etc code/ISO_Storage device-config:legacy_mode=true content-type=isoTo make it an ISO library. Nothing is listed in there. Is it me or this so much just to create local storage?
The reason being that LOCAL repo's aren't supported, is that it literally takes nothing to share out a drive from a windows desktop and connect to it via XenCenter (or XO).
It's a 5 minute process.
Yeah but there isn't a single use case for local storage? Ever?

How do you handle permissions? This is my first time
-
@wirestyle22 If you made the wget with root, no problem, XAPI is running as root too (and default perms in here should be OK). So after you Wget is done, just
lsto be sure your ISO is here. Then, rescan the SR with the appropriate interface (Xen Orchestra or XenCenter). -

I'm not home right now to really go through it unfortunately. Maybe I'll configure remote access tonight so I can tinker. Everything for me currently is being run in root. Not trying to complicate my life too much yet
-
@wirestyle22 in truth, you can just create an LVM volume with a filesystem upon it, store the ISOs there and mount it as a SR. The real issue is that at the reboot XS7 will stop doing consistency check of LVM. That's totally repeatable.
-
That sound really overcomplicated to serve just some ISOs. I wonder if I won't offer a "public" NFS in read only with most popular ISO, a kind of ISO as a service
-
@olivier I think that the right way to provide a "templatized" VM is to customize a cloud OS image via libguestfs or similar tools, going through the whole installation process is just nonsense for VMs. Poor windows users…
-
@Francesco-Provino Solution is creating a template with CloudInit process, then Xen Orchestra can do the rest. See https://xen-orchestra.com/blog/full-cloudinit-power-in-xenserver/

My new take on XS is to not touch XS. It's like Fight Club.
The easy way for ISOs I found was...
a) set up a new Linux Mint VM
b) set up an anonymous share
c) add ISOs
d) doneWindows works, but it;s hard to do anonymous shares, I've always found. You could create a user, which I did initially, but I've since moved to a small Mint instance and haven't looked back.
-
@olivier or via cloudinit, exactly, I just forgot to add it.

The thing is we already have CloudInit support, so it would be a shame to not using it

That's a way to do it also yes. In general, I've got always a physical machine (eg for backup) with enough space to do that. Doesn't require much bandwidth and power to simply share ISOs.
-
Thoughts @scottalanmiller ?

Yeah, just giving options.
There are many.
Anything that can share files would work. I just find sharing files anonymously through Windows maddening.

I have no idea, last time I tried it was 10 years ago.

It's probably why you moved on!

If I shared my SSD on my desktop how would I handle the permissions for mounting in XS? I did attempt this but it failed. Granted I had to leave immediately after and didnt get the chance to troubleshoot it.

You could create a local account on your machine, give it access to the shared directory, and use that when you mount from XS.
That's what I did initially.

I'll give this all a go when I get home and report back. Thanks everyone!
