Been running into a number of issues with upgrading proxmox5.

Issue #1
- Update to latest proxmox5 and after the update the kvm_intel kernel module is not being loaded. I see a message like this when starting the VM.

Could not access KVM kernel module: No such file or directory
failed to initialize KVM: No such file or directory

If I run "modprobe kvm_intel" the VM will start until the next reboot. Everything was working as expected before the update.

To get away from this issue, I load the kvm_intel kernel module, then update-grub and update-initramfs -u. Reboot and everything seems ok. Sometimes I have to do this twice before it sticks. This has happened in prox4 -> prox5 and prox5 -> prox5 upgrades.

Issue #2
- Update to latest proxmox5 results in different kernel versions. In my test 3 node cluster I updated this morning, 2 nodes ended up with 4.13.13-5-pve and 1 node ended up with 4.13.13-4-pve.

4.13.13-4-pve

For the module part, just add it to /etc/modules. It's strange that the error occurs, but that'll fix it

For the other part, maybe one version was removed due to some problems?
 
New kernels should be pulled in as dependency with updates to the `proxmox-ve` package, which should be at 5.1-36, can you check?
