Citrix Hypervisor 8.0 landed
-
I throw down one of my xcp-host to setup a not-nested-virtualized xen-8 in order to test RBD speed. Performance are about 4x slower than they should be but at least it run almost like a standard local disk.
dd if=/dev/zero of=./test.img bs=1G count=1 oflag=dsync 1+0 records in 1+0 records out 1073741824 bytes (1.1 GB) copied, 1.86156 s, 577 MB/s -
Have anybody tried xcp 8.0 with the intel x56xx series cpu?
why is support for this cpus dropped, are there any technical behind it or just that they are old and considerd Legacy?
i would like to know if this cpus have been tried with this veriosn of xcp.

You should run tests with 10 or better 100 - if you can.
That also diminishes influence of any caches (on source and target!). -
@Prilly XCP-ng 8.0 (the Host) is not released (even not an alpha or beta), I only released XCP-ng Center 8.0 (the Windows Client)
-
@Prilly the same thing I'm wondering what could be wrong with that cpus beside of high power consumption which is obvious becouse those cpus are about 7 yrs old.
VmWare is working with that cpu but 6.7 installer says that the support for that cpu will be dropped. And that would be not good for me becouse I would need to replace all of my servers which is not the case.

I hope XCP-ng will support legacy CPUs as I have E5-24XX series servers
I guess they will work fine but as they are not supported officially ...E5 arent legacy. Xeons x5xx are.

According to the XS HCL Citrix Hypervisor 8.0 is supporting Dell R420 servers but not Dell R430 (same model, but newer, you can still buy the R430). The newer R440 is also supported. This seems very odd to me. Has anyone any idea why this is the case?
-
While you're waiting for XCP-ng 8.0 beta, what about testing the latest security update to help us release it fast?

Thanks!

Been running CH 8.0 for a week to test it out. There's an issue with the guest tools. performance is slow because the guests I/O isn't "optimized"
going to revert back to xcp 7.6 today.
-
@nuts23 testing what? CH 8.0?
-
@olivierlambert yes, sorry, the Citrix Hypervisor 8.0
-
Guest tools on Windows (I suppose) aren't working well?
-
@olivierlambert yep
-
Have you used Citrix tools directly from CH ISO or something else?
-
yes, I used the ones in the ISO and through the system. I also tried some older ones.. In the end the system never recognized that I had the proper ones installed. Tried with 2 different windows VMs. Server 2016 and Win10
-
Can anybody that has the means try to run Citrix Hypervisor 8.0 on those legacy 56xx series CPUs?
-
@nuts23 did you use fresh installed windows or "used" ones?
-
@Prilly I installed Citrix Hypervisor 8.0 on my Dell C6100 which is running L5630 CPU and it booted just fine.
-
@crash you can even try with XCP-ng 8.0 now
(still beta but will be useful to try) -
@olivierlambert @prilly Just loaded the XCP-ng 8.0 successfully on a Dell C6100 with 2 x L5630.
No errors during install, and boots up just fine for use.
