I resolved it, logged in the XCP-ng console and set the NTP servers to default. All good now.
Thanks

I ran the command you sent but same result trying get the fix . see attached pic.

Thanks for you help, trying to get this server in production.
@Andrew said in Windows 2025 Standard 24H2.11 (iso release of sept 25) crash on reboot with "INACCESSIBLE BOOT DEVICE 0x7B" in XCP 8.2.1 and XCP 8.3:
fixvwc patch
Having the same isaue with a new Windows Server 2025 VM , tried to get the updates but it failed also, see attached

I have 7 other Windows VMs that are not restarting and the host is not restarting, just one of VMs on it is having this issue. It reboots every 10 -15 min.
Hola ,
One of my Win10 VMs is rebooting about every 15min. XO task shows this every few seconds API call: host.restart. Below is the raw log for it. Any ideas on how to resolve please?

Yes thanks Oliver. My next mission is to master backups!!
Thanks for the quick response. The issue with making the changes seems to be my input to XO remotely via ScreenConnect, sometimes my keystrokes with numbers do not enter. I started a new ScreenConnect session and I can make the chamges to ram now.

I created a Windows 10 VM (uefi,secure boot and tpm) with sysprep applied . I shut it down and created a copy on the same host(not fast clone), I can not increase the RAM on the either VM, tried when they are both off , I cannot change the value in the RAM field in advanced setting.
I resolved it, logged in the XCP-ng console and set the NTP servers to default. All good now.
Thanks

I just installed 8.3 and xoa community how do i fix this error in displayed in xoa host - Host time and XOA time are not consistent with each other
Thanks
