Rescue Raw VM Disk from Proxmox 4.3

[sdet00]

Hi everyone,

I have an unfortunate situation where my Proxmox 4.3 installation failed to bring up the WebUI and VMs after attempting to update the system. I was confronted by a half-complete update caused by unmet dependances for zfsutils, and after attempting to remove zfsutils I somehow managed to remove pve related components. I completely stuffed it. Bah.

I have a 5 month old system image of my proxmox setup which I am restoring now, but I'd really like to restore one VM which I have been updating recently. Is there any simple and easy way to do this? I am a little bit of a Linux rookie but I am learning. Even better if I could move it to my Proxmox 5.1 host which is destined to replace this current system. Any advice would be very welcome! I have a spare Linux Mint PC that I can connect the disk directly into if that helps.

Also, if anyone has some advice on how to automatically backup my entire Proxmox installation that would be really great, unfortunately the only way to do this at the moment is to power off the system, pull the disk and make an image on my spare workstation which is quite a hassle.

If it helps - I can boot Proxmox and get network connectivity and access to storage, but I am unsure what to do from there since I cannot access a WebUI to start the VM.

Hi,

there is no need for a new installation.
Boot your PVE.

run the following commands

echo "deb http://download.proxmox.com/debian jessie pve-no-subscription" > /etc/apt/sources.list.d/pve-install-repo.list
wget -O- "http://download.proxmox.com/debian/key.asc" | apt-key add -
apt-get update
apt-get dist-upgrade
apt-get install proxmox-ve ssh postfix ksm-control-daemon open-iscsi systemd-sysv

If an error occurs post it back.

Thanks for the reply! Unfortunately I was met with problems. See the following terminal output - any ideas?
