+Kernel Upgrades and Reboots
+-----------------------------
+
+In case of a kernel upgrade (package `pve-kernel`), reboot your host to avoid issues.
+
+See which kernel is running:
+
+----
+# pveversion
+pve-manager/6.4-6/be2fa32c (running kernel: 5.4.106-1-pve)
+# uname -r
+5.4.106-1-pve
+----
+
+And check which ones are installed:
+
+----
+# ls -1 /lib/modules | sort -V
+5.4.73-1-pve
+5.4.103-1-pve
+5.4.106-1-pve
+5.4.114-1-pve <--- new kernel installed but not running
+----
+
+If the latest installed kernel version does not match the running one, then you should reboot the host.
