★ UIS new VM cannot start error, indicating that the physical node does not support KVM

Null

New deployment of UIS, create a new virtual machine on a node, and when starting the virtual machine, it prompts that kvm is not supported.

Installing a virtualized server requires CPU support for virtualization technology, and the BIOS needs to enable virtualization configuration.

For servers with X86 architecture, the CPU must support Intel-VT (Intel Virtualization Technology), which allows for single CPU simulation of multiple CPUs in parallel, enabling the simultaneous operation of multiple operating systems on a single machine. Servers with ARM architecture CPUs need to support ARM VHE virtualization extension technology.

It was learned during on-site communication that the BIOS configuration of the host was initially not enabled for virtualization, but after deploying UIS, the BIOS configuration was modified and the host was restarted.

However, the problem still persisted after the restart.

Upon checking the BIOS configuration, it was found to be consistent with that of other normal hosts.

However, when reloading the kvm module for the host, it still prompts that virtualization is not supported.

Therefore, it is suspected that although the BIOS configuration has been successfully modified, it has not taken effect.

Upon consulting the hardware side, it was found that the BIOS needs to be reset (enter BISO and press F3 to reset).

After resetting the BIOS, restarting the server resolved the issue.
