Depends on what you're looking for. I require KVM (for BSDs) rather than OpenVZ (Linux-only). I have a VPS at each of the following:
I've been pleased with OVH if their locations meet your needs, though I had to hack OpenBSD onto it (BSDs not supported). I've been pleased with their connectivity & DDoS mitigations.
For cheap disk-space on slower HDD hardware, InterServer has storage servers at one of the best prices I've found and they let me load a boot .iso
(by disk-image URL) for installing FreeBSD or OpenBSD. I don't remember if I had to open a ticket to load the .iso
though.
I also have one VPS host at RackNerd which has some pretty good prices and support for installing from a custom .iso
. Base prices are nothing spectacular, but they often have seasonal coupon-codes for notable discounts.
I wish I could recall off the top of my head which of those gave me some IPv6 trouble (mostly a matter of failing to provide the IP/mask/gateway information via DHCP6/SLAAC or in the control-panel).
@ed1conf @mwl OVH does IPv6 really weird.
Whoever architected that a) doesn't understand subnets, and b) was fairly afraid of *running out*.
