Guest UEFI Secure Boot looks like a great guide. Everyone needs to read the "Boothole and fallouts" section.

@tsettle Glad to hear this. I had tried getting GNS3 working for a long time but gave up and ran it under ProxMox. Is it still working? Do you mind sharing the guide you used? I have always thought it cool to havae a Xen Orchestra recipe / ansible build.

Rule out problems with your old firefox profile by creating a new firefox profile dedicated to non internet stuff. We should always use a dedicated profile for internal only websites such as your firewall webpage, XenOrchestra, freeNAS, and so on.

firefox -no-remote -new-instance -createprofile intranet
firefox -no-remote -new-instance -P intranet

Does udevadm work in XenServer? I am sure what I am trying to do is not supported, but would still think it would work.

More often than i care to admit, i need to get to the serial console port of various network switches. So i had a Linux box with a USB hub and . With a normal CentOS6 and CentOS7, i had given all kinds of /dev/ttyUSB_aliases to each different RS232 cable.

[xcpng host]# ls /dev/ttyU*
/dev/ttyUSB0
/dev/ttyUSB0_ServerNetworkSwitch0
/dev/ttyUSB1
/dev/ttyUSB1_StorageNetworkSwitch1
/dev/ttyUSB2
/dev/ttyUSB2_StorageNetworkArista40Gb_Only200dollars

Each of the cables has a unique embedded serial number and I use the serial number to name each cable.

[xcpng host]# udevadm info /sys/bus/usb/devices/2-4.3
[xcpng host]# udevadm info /dev/ttyUSB0 | egrep  '(SERIAL)'
E: ID_SERIAL=FTDI_FT232R_USB_UART_AM00I2M5
E: ID_SERIAL_SHORT=AM00I2M5

Adding the following to /etc/udev/rules.d/57-usb.rules does not give me the symbolic links.

ENV{ID_SERIAL_SHORT}=="AM00I2M5", SYMLINK+="ttyUSB_AM00I2M5", SYMLINK+="ttyUSBARISTA1", SYMLINK+="ttyUSB_ARISTA1_Storage10GbX48"
ENV{ID_SERIAL_SHORT}=="AK08S3EG", SYMLINK+="ttyUSB_AK08S3EG", SYMLINK+="ttyUSBARISTA2", SYMLINK+="ttyUSB_ARISTA2_ServerSwitch_TopOfRack"
ENV{ID_SERIAL_SHORT}=="AK08S4NU", SYMLINK+="ttyUSB_AK08S4NU", SYMLINK+="ttyUSBARISTA3", SYMLINK+="ttyUSB_ARISTA3_Storage40GbX32"

udevadm trigger or unplugging the USB hub to force it udev to reevaluate does not result in my sanity shortcuts:

[xcpng host]# find /dev -iname 'ttyU*'
/dev/ttyUSB2
/dev/ttyUSB1
/dev/ttyUSB0

@encryptblockr hope to try the same with their even smaller "CORE" images. There is not an .OVA download but .xz downloads that when expanded have .img .

https://cdimage.ubuntu.com/ubuntu-core/22/stable/current/ubuntu-core-22-amd64.img.xz

and

https://cdimage.ubuntu.com/ubuntu-core/22/stable/current/ubuntu-core-22-amd64+intel-iot.img.xz

cloud-init seems to require experimentation and these small images boot quickly for me.

Are you then following Fohdeesha's instructions?

@encryptblockr Did the new 2022-11-24 images work better?
Did you remember to install cloud-initramfs-growroot ?

packages:

• xe-guest-utilities
• cloud-initramfs-growroot
• cloud-initramfs-rescuevol

@tony ssh is not always an option especially for premade ISOs from vendors. DellOpenManage VM for instance was vmware only and ssh was not enabled.

• Win2019 msconfig.exe seems to be in "safe-mode part way" because msconfig.exe will not let me choose a normal startup. It reverts back to "Selective Startup".
• "Normal Startup" radio box will not stick. Click "Normal Startup" radio box and then "OK" button to exit msconfig.exe. Relaunch msconfig.exe and notice it reverted back to "Selective Startup".
• The Win2019 VMs seem to run ok, but some hard to resolve problem with an application I trying to resolve.
• Anybody else see this issue?
• Have no idea if this has anything to do with XCP-ng or not.
• Windows update drivers.

Guest UEFI Secure Boot looks like a great guide. Everyone needs to read the "Boothole and fallouts" section.

@stormi Installation of MS KB4535680 is failing for us as well as many others. To be clear, we have not downloaded the latest patches mentioned in XOA. Will simply installing the latest ca-certificates (dated Sept 14, 2021) and updated grub-efi (dated June 29, 2021) along with the other updates such as xcp-ng-release-config 8.2.0-8 fix this or do we have to manually make changes mentioned above as well?

I expect having Windows reboot into UEFI and configuring the UEFI to attempt secure boot will be necessary no matter what. Meeting with a software vendor later today and they may ask why MS KB4535680 is not installed.

@olivierlambert
So 39% on the Citrix host shows as 0% in XO,
but 51% on the Citrix host shows as 100% in XO.
Got it. Hopefully, we can put that nonsense behind us soon.
