256mb KVM. how much will it suck?
Tempted to try one of those low end KVM for.. well, why not?
I have bunch of 2-4GB KVM/Xen instances where the overhead is almost negligible. But how about 256mb?
Im planning to use it for VPN and proxy (good for shadowsocks), as well seedbox (rtorrent+nginx+php) to waste the rest of disk space.
In OVZ, 256mb is enough for lots of things. Will the experience differ much in KVM?

KVM has slightly more overhead than OpenVZ as it runs in a full virtualizaton mode. There are many people that use KVM on a 128MB RAM VPS although you may not be able to run all the application(s) you stated.
How much exactly the average (pardon the oxymoron) overhead? Never measured it on my servers.
On a 128MB KVM VPS, running Debian 7 32bit it will use about 10-20MB of RAM off a fresh reboot (this is on a clean install). The difference is pretty minimal, not negligible though. I only use KVM when I absolutely need to.
I have a bunch of 128MB KVMs and even one or two 64MB, all fine.
Ooh. then its totally not as bad as I thought!
I much prefer KVM though. I use shadowsocks, which much of kernel optimization is otherwise not accessible in OVZ.
I much prefer smaller VPS, so I can afford more of them in various locations. The only issue I've ever run into with 128/64MB is installing from ISO rather than using a template. It can suck if you're using something like Centos where the installer requires more memory and refuses to cooperate. But most hosts give you an option to go with a template.
Back in the day when TacticalVPS was still alive Ian temporarily gave me 512MB of ram to do the install and then backed it down to the subscribed 128MB.
Yep, has a CRT screen and all!
Can PM me some providers that still offer these VMs? Love those tiny VPSes
Below are some KVM VPS that I am using it and so far so good.
