You're using an OpenVZ-based VPS, and on this VPS your root filesystem isn't really a filesystem, but a directory on the host. That directory on the host has run out of disk space. This is a strong sign that your provider has significantly overcommitted resources and isn't monitoring them well, or at all. The replacement for simfs, known as ploop, is more ...

RAM and SSD are orders of magnitude different in speed. I would suggest getting more RAM. If you need to swap, that's fine, but you KNOW that the best long-term solution is more RAM.

Setting aside the fact that you can't connect to your Azure database from the application on your VPS, do you think this will actually improve performance? You haven't specified who your VPS provider is, but it sounds like they will be in completely different datacenters. Who knows, they could even be in completely different continents!

For example, the order of operations is: # Freeze guest filesystems virsh domfsfreeze $VM_NAME # Create snapshot qemu-img create -f qcow2 -b $VM_NAME.qcow2 ...

Whether it is OK to host both staging and production on the same VPS is entirely up to yourself. There's certainly no laws prohibiting it, but depending on your situation there may be very good reasons for not doing it.

Currently your email is going to mx0.123-reg.co.uk and mx1.123-reg.co.uk as indicated by the MX records in your DNS zone. If you want your email to go to the host named mail.yourdomain.com (as represented by the A record in your DNS zone) then you need to change the MX record(s) to reflect that. The MX record is used to designate the host or hosts that ...
