@Dashrender said in XenServer 7.0 issues on HP Elite 8100, 6.5 Flies.:

I have a HP EliteDesk 800 G1 SFF as my XS 7.0 test box. Works great!

I don't see any issue with a lab box being PC based.

Yeah. My "oh s***" box is a Dell T3500. It stood in for the server while it got upgraded to XS7 from XS6.

I found the process I had used previously. Here it is here. Summarized below.

Make sure the VM in question is shutdown.
From the console xe vm-shutdown uuid=<UUID of Your VM> xe vbd-list vm-uuid=<UUID of Your VM> params=uuid,type xe vbd-destroy uuid=<UUID of Your CD/DVD> Of critical importance do not select Disk, ensure you select the UUID of the cd Repeat step 4 as many times as you have CD's that are unusable. Reboot the VM and add the device again.

Seems that way, but worth some testing.

I'm going to test the "add folder to SR" theory soon.

Then I can move on to SRs and partitions.

Does it have better performance & is it easier to setup?

That is all dependent on how comfortable you are with software / hardware raid.

Even for software RAID experts, hardware RAID is easier.

well yeah - it's practically plug and play - so few options.

Plus, in hardware RAID (assuming the chassis supports it) you get hot swap, something you don't get with Software RAID.

All enterprise software RAID has hot swap and always has. Only FakeRAID doesn't offer that and even that sometimes does. Hot swap is basically ubiquitous. Even ridiculous Windows software RAID has hot swap.

excuse me, I used the wrong term - I meant Blind swap - the lack of need to tell the OS to demount the drive before you pull it from the system.

Yes, now that software RAID generally lacks.

What do the logs say about the system going down? I'm guessing that it is going down for whatever reason there is then a RAID issue.

@ntoxicator said in Get Large Disk Images on XenServer 6.5 on Local Filesystem?:

@Scale computing nodes...... same limitations I presume?

Sorry for taking a week to see the mention. Thanks for thinking of us.

No, the limitation does not exist on the Scale HC3 clusters. We do not have artificial size limitations. We have tested VMs much larger than 2TB without issue.

@olivier said in XenServer Export Performance Seems Poor:

You can create a basic backup schedule and de-activate the compression, then run the job manually. You'll have an export without compression.

When I was running my test, it seemed the exporting directly from XC was quicker than running a one time backup from XO of the same VM to the same location. The export of a small VM (I set it up just for testing this) was about 6 minutes, and the backup was 13.

But it sounds like what you are saying is that it should have been the opposite.

And that didn't take your VMs down?

My situation wasn't a snapshop - it was a fast copy.. so I'm not really sure.

@Danp said:

@johnhooks On a non-running VM, there's a "clone" option where you can choose either fast clone or full disk copy.

I feel like such a moron. That's such an obvious place and I didn't even notice it. I've just been using the regular copy function like a dolt.

@travisdh1 said:

On a somewhat unrelated note, thanks for getting me to look at the /var/log directory on the XenServer here. Had a bunch of old logs clogging things up (500MB on the tiny little root partition.) Moved those off to my workstation for now, probably need to take some time and see what's going on.

Glad my freak out could help ya out 🙂

I'm watching the videos trying to figure out what it does. Looks like a decent product but haven't seen any single pane of glass stuff yet.

Did you at least find one compelling feature?

Not yet.

Used these instructions to create the ISO Store.

XO makes it easy. You can just create one with their interface.

I suppose you could install the XO VM using a URL to pull the ISO for installation.

Just a guess..

@it-admin 4 years later, I encountered the same issue that you did.

The solution for me was do do a PCI passthrough of the physical NIC directly to the VM. This bypasses all virtual switching inside Citrix Hypervisor. I posted the exact steps to implement PCI passthrough on Citrix Hypervisor 8.2 here:

Did you not have somewhere to jump off of?

XS/XO/XOA is all great, but seriously the thread count is stupid. The knowledge is lost in all the noise.

@halizard Awesome, thank you and your group a crap ton for me.

Gives me stuff to work on!

Happy to see it tested intensively 🙂

I hit the store last night and spent $23 on a 32 GB, not point in not just having plenty of extra space.
