Migration from openvz

Question

linux

Good afternoon, hackers.

I'm thinking of a new virtualization tool to replace openvz for developer work machines.

The main requirement
is the ability to mount the FS of the virtual machine to the FS of the host machine. Of course, ssh is also possible, but it would be better to have native, full access, like openvz.

I myself look towards KVM for now.

Answer 1

Why are you giving up openvz?
You can migrate to LXC, as well as OS-level virtualization, but upstream from 2.6.32 kernels.
Xen and KVM - getting full access to the FS of the virtual machine is not a problem, but only in exclusive access - the FS is mounted either to the host or to the virtual machine.

Answer 2

There are no problems with memory allocation in Openvz.
For example, you can do this - hastebin.com/rurevahadi.vala
But with ipv6 there is f*ck, yes.
And so, KVM. If different kernels are not needed - lxc with lxctl. Get along on one machine more than.
In both cases, access to the FS only if the virtual machine is turned off. In LXC.tl, the fs is mounted on the host, but attempts to write it there are no good since. Virtual machines do not lead.
