... the uname -r command provides the name of the host kernel, right?


Basically - yes, but read my next comment.

Then I reboot the guest. Is the guest Linux version changed?


Automatically - no, but we have a /proc/sys/kernel/virt_osrelease file. Writing to it causes all VEs that start after the change get the new uname -r. Further file updates do not affect already running VEs

Quote:

If so is it possible to check the running version?


Considering the /proc/sys/kernel/virt_osrelease screwup ability, you have no way to check the actual kernel version from inside the guest.
