Updated and working so far

I'm not sure to get everything you wrote here.

mv: cannot stat ‘/usr/sbin/lvmetad’: No such file or directory is identified and reported to Citrix. It's not XCP-ng specific.
What do you mean by "test connection"?
Does USB passthrough worked before on 7.4.1?
What kind of modification did you do on 7.4.1 before updating? was it "vanilla" or you installed/configured some stuff on it?
apcupsd doesn't sound coming from vanilla XCP-ng

Ok

What do you mean by "test connection"?
The hypervisor successfully connected to the NAS, for the purpose of importing a saved VM. The VM started OK.

Does USB passthrough worked before on 7.4.1?
Only showed the UPS usb device, never the U-Blox AG , this is the same situation with 7.5 (Thread USB Passthrough 20 Jun 2018, 14:13)
Both versions show the device U-Blox AG using the lsusb command.

What kind of modification did you do on 7.4.1 before updating? was it "vanilla" or you installed/configured some stuff on it?
Installed apupsd (Thread Apcupsd UPS support 15 Apr 2018, 17:33)
The upgrade appears to have removed the apcupsd daemon, /usr/sbin/apcupsd, but not the service definition

Citrix did not support apcupsd, but Citrix upgrades in the past did not remove it.

apcupsd doesn't sound coming from vanilla XCP-ng
No, but ups support is essential for safeguarding the system.

Aimee

olivierlambert

Yeah but Citrix isn't relying on Yum to upgrade If you want to be "defensive", then upgrade via the ISO on boot, not on a live system

Problably a dependency thing.

Aimdev

@olivierlambert
Hi

I do not quite understand your answer, please can you clarify.
The system was clean installed from 7.4, 7.41 to 7.5, all xcp-ng.
The ony addition was the ups yum , as described in my thread.
Are you suggesting that a clean install will

fix the pass through for the Ublox?
To get ups support I must repeat my extra ups software install,?
unless xcp-ng is going to provide an alternative package for UPS support?

Thanks

Aimee

olivierlambert

Nope
Yes.

This thread is having several discussions in parallel. If nobody minds, I'll move them to separate threads soon.

Update: done.

Update with HA enabled / or not upgrading master first : https://xcp-ng.org/forum/topic/265/issues-when-upgrading-with-ha-enabled
USB passthrough: https://xcp-ng.org/forum/topic/266/usb-passthrough-test-reports-in-7-5rc1

I pushed several update candidates to the RC in the updates_testing repository:

vhd-tool fixing two bugs:
- "VDI import seems broken for large VHD files" https://bugs.xenserver.org/browse/XSO-868
- "VDI export fails with VDI I/O error" https://bugs.xenserver.org/browse/XSO-873
xen security update

To test: yum update --enablerepo='xcp-ng-updates_testing*' and reboot.

What we need is to make sure they cause no regressions.

Thanks!

@stormi said in XCP-ng 7.5.0 Release Candidate:

yum update --enablerepo='xcp-ng-updates_testing*'

Is this interfering with the ZFS packages or there is no issue to do it? (especially blktap)

stormi

@olivierlambert No issue to do it.

olivierlambert

Great!

second server has also been updated successfully.

the third server I use pci passthroug for 2 DVB cards.
So far that was excellent under 7.4.1.

Since upgrading to 7.5 I get the following error if i want to start the vm with the passthroug pci devices:

vm.start

Does anyone have any idea what that might be?
does anyone have an upgrade to 7.5 with pci passthroug on the run?

Thanks and Greetings

Populate on Demand

Do you know what's this? It seems incompatible to have it enable in parallel with PCI Passthrought.

edit: it seems your dynamix min/max and static max aren't set at the same value.

christianuhlmann

@olivierlambert

Hi
After a bit of googling on populate on demand I realized.
strange that it worked under 7.4.1.

if I understood correctly, it is the dynamic ram assign with min / max.

after I entered a fixed size for ram, the start worked fine.

thank you for the great work

Christian

olivierlambert

I think ballooning + PCI passthrough can cause some crashes, so that's why there is a check to avoid using both at the same time.

Bungo

Updated via YUM, all seemed to go well, except the xcp-ng tools ISO only seems to have the Linux directory and the readme.txt file on it, no windows tools.

Guests on 3 hosts same.

file appears to be "guest-tools-7.29.0-2.iso" in /opt/xensource/packages/iso

cheers.

stormi

The windows tools are not free software, we can't distribute them. There's a way to install them though: https://xcp-ng.org/2018/04/23/the-future-of-vm-tools/ (see "a better model")

Bungo

The readme doesn't say that. Might need to adjust it.
