Wow.. fab news .. well done all!

@dthenot and @maevaram

Congrats to @dthenot and @maevaram, hope you both have a blast in your roles and good luck!

Its all about XA/XD I'm afraid but it does state year end 2019 for the next LTSR.

"Long-Term Service Release News

For those of you on 7.15 LTSR — one of our most popular releases — we have some exciting news about our next LTSR availability. We’re planning our next LTSR for year-end."

@olivierlambert

Citrix, have recently announced via blog post that the next reported XenApp/XenDesktop LTSR release is due end Q4 2019 so its possible CH8.1 might show up at the same time.

@LonnieTC , as @nikade stated you can sign up and get a 90/180 day trail for XA/XD and all you'll need is a mycitrix account to do so and rinse and repeat for a POC or Lab.

Yep.. Its called XenApp/Xendesktop aka Citrix Apps and Desktops, MS RDSH and UDS Enterprise all are fine on XCP_NG ... although I only used XA/XD/RDSH on XCP-ng.

@Arvee

We were always deploying using Xendesktop/XenApp - performance once configured correctly - GPO's HDX policies was usually very good - apps workloads Autocad, Revit and Inventor Pro. No longer have access to all the tweaks.

Not sure how you'd tune and tweak RDP to improve the performance.

@Arvee

Well done.. the S7150x2 should be a a fair bit faster than the K2/K1 grid cards. For CAD/Architectural workloads we found it as fast as Nvidia M60 and sometimes faster .. using the same GPU profile types.

@olivierlambert

Good to know that they're already working on it for Xen. Surprised that none of the Citrix bod's at the event mentioned it. Looks like the best way to do get around the massive performance hit without switching to AMD !

Folks... was at Citrix event today and the morning was a talk by LoginVSI looking at the impact of the latest security patches for Intel CPU's and the performance impact server on EUC work loads and server scalebility on the Hypervisors. According to the presenter all the Hypervisors (Hyper-V, VMware ESX and XenServer) that they were testing were seeing approx 20-25% decrease in performance when using Intel based systems. What I found interesting was VMware has developed a new scheduler, SCAv2 to help reduce the impact although no numbers where mentioned. There was no mention of anything of th sort for XenServer or HyperV.

https://blogs.vmware.com/performance/2019/05/new-scheduler-option-for-vsphere-6-7-u2.html

According to that blog post .. the impact using the SCAv2 was reduced to 11%.

@olivierlambert

AMD were making a lot of noise about the Pro V430 when it released and how it stacked up against the equivalent NV card. Not sure on where to get the Pro V430 .. those would be have been provided by AMD and eventually alway had to go back ...

The S7150x2 and other MxGPU's are available from the likes of Scan, I'm surpised that they don;t sell the Pro v430.

I found the Pro v430 being sold ar Insight and its spendy $9k - not sure what the performance would be like and is it worth 3x the price of the S7150x2 ? The S7150x2 was a good as the Nv M60 in our testing.

You should be able to get the S7150 and get 3 for the price of a single Pro v430 from most resellers:

@biztems , @olivierlambert

Sorry chaps .. I'm away from home with minimal internet access. I did mean the S7150 series but stubby fingers always get in the way. The new Radeon Pro v430 should also work with XCP-NG. You'll just need to install the latest Xenserver drivers from AMD. Unfortunately I no longer have access to any of the AMD Mx GPU's otherwise I would have been happy to test etc with XCp-NG..

@olivierlambert .. think it might be worthwhile getting in touch with AMD and Intel as a partner just to make sure that nothings a miss in XCP-NG to get those GPU's to work out of the box. I'm sure that they do.

Not sure if Citrix would be happy though!

Unfortunately K1/K2 Nvidia Grid cards are only supported on Xenserver 7.1, so if you want to be using them you'll have to go to the latest 7.1 LTSR release. Think that was a decision by Nvidia so that they could change the licensing model for their successor M60 grid cards.

If you want an equivalent to the K1/K2 your only option is the AMD MxGPU's - performance wise the S7510 FirePro is as good as the Nvidia M60 and without the additional licensing.

Nvidia Quadro and AMD Vega/RX cards for pass through only will work with XCP-NG.

@olivierlambert
I'm assuming that sync is enabled by default ?

@olivierlambert
(1) Missing the ZFS packages from the base install.
(2) Needed a "yum clean all" to be able to install zfs packages.
(3) Needed to manually import the ZFS zpool

I'm a noob with zfs so had to work out how to import an existing zpool and once thats done it can be repaired/mounted.

@stormi yum clean all worked. Installed aok and modprobe zfs doesn't complain so that's all good.

A repair of the ZFS SR fails with the same error and "zpool status: no pools available" and "zfs list no datasets available".

I'll open a new post if I can't get it working rather than replying to this one.

Update: fixed the issue ..

@stormi still broken .. same error

@stormi Ok..... silly me .. will wait for you to give the aok.

@stormi Thanks for the quick reply .. tried the yum install zfs and it errors with the following:

Installed fine on one of my Intel X56XX based system and the system boots into XCP 8.0 although the zfs local storage wasn't mounted and a repair fails as well.

modprobe zfs fails with "module zfs not found"

Is there any updated ZFS documentation for 8.0 that would help?
