Why does Proxmox crash on FastVPS?

Question

linux

The situation is as follows - there is a dedicated server (PX-90) on FastVPS. The server had a standardly deployed Debian 7, but it became necessary to install Proxmox in order to serve a dozen virtual machines. KVM was ordered, Proxmox 3.4 was installed with zfs as the root file system, a couple of virtual machines were configured, however, after a day of uptime, the server ceased to be available over the network, however, in the personal account it says that it is on, the again ordered KVM shows a completely dark console and does not react in any way for me, a software reboot does not help - only a hard reboot helps, after which the server works again, but only for a short time (about a day) - then the same situation. I thought that maybe zfs could have such an effect, I moved Proxmox now with ext3 - exactly the same situation. I checked the hard ones according to SMART - there is nothing suspicious. There is nothing suspicious in the logs. I thought about contacting the host, but I was confused by the fact that the original server with Debian 7 worked without problems. Has anyone experienced similar?

Answer 1

Yes, you can look for the same problem on the toaster in my questions, as a result, nothing is being treated, the problem is in the openvz kernel, that is, it crashes both on proxmox and centos with the openvz kernel.
Alas, only change the server.
Probably a problem with the ivi bridge processors, but I can’t say
for sure. px60 and 70 work with proxmox without problems.

Answer 2

EX40 on hetzner with Debian 7, works flawlessly with proxmox

Answer 3

Not as an advertisement, but I've been successfully using Hostsailor's Proxmox DS for over a year now .
It is possible to take a good configuration within 100-150$/mo.
Not a very fresh line, of course, but confidently working HP Proliant branded servers.
And iLO, again, is for everyone.
