  Great projects have great documentation. Is XCP-ng a great project?

  No you can't that's why as an introduction we warn that you need to make a choice, not mix them. We might be able to make our agent work with Citrix drivers in the future, but for this we need a dev.

  Oh ok.. I know why... mount.ceph came in nautilus release. I have edited the post to install nautilus. Unlike RBD, CephFS gives browsable datastore + thin disks and is super easy to scale up/down in capacity with immediate reflection. I'd spend some time later to implement "Scan" and have a proper SR driver. Thanks for testing and feel free to raise if you come across further issues.

  @peder Thank you. Unfortunately, that machine is in datacenter so dont have physical usb access. Nevertheless, I found a way to do the conversion. Seems as XenConvert 2.3.1 is capable of doing it, however, its only that version that does it, the rest are all different. Therefore, issue resolved for conversion, but i'm still wondering if im the only one that had that issue or is it quite common given the system version I have to xcp and the center.

  A slightly less hacky work around for USB v1 passthrough based on the issue I created: --- /opt/xensource/libexec/usb_scan.py 2019-11-04 10:03:02.000000000 +0000 +++ /tmp/usb_scan.py 2020-03-01 17:32:29.266317478 +0000 @@ -152,10 +152,11 @@ _CLASS = "bDeviceClass" _CONF_VALUE = "bConfigurationValue" _NUM_INTERFACES = "bNumInterfaces" + _USB_SPEED = "speed" _PRODUCT_DESC = [_DESC_VENDOR, _DESC_PRODUCT] _PRODUCT_DETAILS = [_VERSION, _ID_VENDOR, _ID_PRODUCT, _BCD_DEVICE, _SERIAL, - _CLASS, _CONF_VALUE, _NUM_INTERFACES] + _CLASS, _CONF_VALUE, _NUM_INTERFACES, _USB_SPEED] _PROPS = _PRODUCT_DESC + _PRODUCT_DETAILS _PROPS_NONABLE = _PRODUCT_DESC + [_SERIAL] @@ -590,7 +591,10 @@ pusb["path"] = device.get_node() # strip the leading space of "version" - pusb["version"] = device[UsbDevice._VERSION].strip() + if int(device[UsbDevice._USB_SPEED]) <= 12: + pusb["version"] = "1.00" + else: + pusb["version"] = device[UsbDevice._VERSION].strip() pusb["vendor-id"] = device[UsbDevice._ID_VENDOR] pusb["product-id"] = device[UsbDevice._ID_PRODUCT] pusb["vendor-desc"] = device[UsbDevice._DESC_VENDOR] in theory any deice which is "low" or "full" speed (i.e. USB1) will have it's version number changed to 1.00 which forces xenopsd to use a USB1 bus. It may have side effects if the driver in the guest relies on the version number so caveat emptor.

  @fibrewire If you're looking at a free way to do so, you can install XOA from the sources and do it through that. I honestly don't miss the updates portion of XCP-ng Center (even after having used it for years in XenCenter). It was very clunky and time-consuming; and, I ultimately ended up scripting a lot of it locally on hosts instead. This is obviously much easier now that it can be done through a simple "yum" command instead of having to pull all the separate packages and install them like XenServer does. XOA will obviously provide that feature through the paid versions as well (if you've already got it). I'm not big on pushing people to XOA from XCP-ng Center, as I still use XCP-ng Center way more than XOA (at least until they push out the new version with the tree view so I can give it a try); but, that's the easy answer to your question.

  Hi. Unfortunately, there's no other way than booting from an ISO to install XCP-ng. You can't convert an CentOS into XCP-ng. The disk layout would not be good, and actually "our" OS runs as a Xen domain.

  No, i tried that and its doesnt work for keyboard and mouse even with the usb policy change, my keyboard and mouse shows up in the gui and VMs start fine with no errors but they still control dom0 and not the guests. it does not matter because the topic is actually about pcie passthrough that refuse to passthrough my onboard moterboard usb. i think there is some configuration that citrix has implemented.

  I

  vGPU require drivers on xen , which will need to work with Nvidia. Unlikely you can get it work as an open source. If you can get passthrough working, I will be very happy.

  You don't need a link. You can simply attach the guest-tools.iso, already present and known by XCP-ng, to the VM and mount it.

  XCP-ng includes Xen as a core component but it's probably not the only component that is involved. I can't answer to the question about "how much" it differs from someone using Xen directly. Someone would need to investigate that.

  CH 8.1 has the same kernel than 8.0. So by default, will have the same too.

  @enes-selcuk I didn't get your point. Do you have a problem right now or did you just want to give advice to other people? I thought your were in trouble (because I did pre-release the XCP-ng PV-Tools, I basically know this stuff (a bit))

  Before applying the patch, in a new pool (during the CH8 update process to XCP8), when moving any VM to the updated host I received the error below. After installing the patch on the master host and restarting the toolstack on the host master and the source host, we no longer notice error, with the migrate process successfully completing. The error condition was the failed shutdown of the VM in the live migrate process. So I think the patch made available actually solves the problem in question.
