First off I was told by the datacenter when I sent a ticket in about crashing on Vmware that it might be a hardware conflict issue and happens a lot. They told me to try Proxmox and I love it. Though the Guest seems to be still locking up. It tends to Lock up and crash guest on Vmware and just lock up more on Proxmox.

The issue does not happen right away it happens overtime with load I assume but I run a couple game servers the standard Minecraft and Starbound. Never had guest crashes on my other vmware box at another datacenter and ran everything with exact same settings as now and not once crash and 90+ days uptime right now when this one is down.

I just ran Memtest from the Ubuntu disc from the base system through that IKVM and it came up with no errors at all.

Server Specs:

  • Intel Xeon Haswell E3 1240 V3
  • 32GB DDR3 ECC 1600MHz
  • 6 x 240GB Intel 520 SATA3 SSD
  • LSI 9271-8i Raid Card /w Cachevault (BBU)
  • 1Gbps Uplink
  • 10TB Premium Traffic

Ubuntu is configured like so:

My Memory test that I actually hope it would fail as renting a server easy have that swapped out:

I hope you guys can help me out. My small gaming community and friends depend on it :)

Hi,
I don't know how it's actualy, but some versions ago ubuntu has an special kernel for running inside a VM.
Without this kernel I run in trouble under load - which solved with the "right " kernel.

Thanks for this info: linux-image-2.6.32-36-virtual I assume that is a apt-get package?


I was suggested by my ISP to try to use container mode. I have never heard of it till last night so I did a ton of research and installed it. Really cool doing it so fast LOL I thought that was amazing... I have a few questions about it.

1) If I set 8 gigs of ram to the container and 100 gigs of space. And I create 6 Containers like this. Would I be able to share all the resources just fine as long as in total it does not pass the 32gigs mark if that is my servers total ram? Also would that be the same for the hard drive space say I had 400 gigs max? If so FRIGAN SWEET! I'm not a seller I use it for personal use for my gaming community but that would be wicked.
2) How secure is the container. I hear if the main kernal got effected everyone is at risk. But how safe am I if I hand my friend a Container account. Could they effect me or screw with me overall? I mean were not talking about security risk of like 0.0001% of an exploit more just could he ruin the server accidentally?
3) Anything I should know about the container performance or anything else while using it?

right, do you have tried it?

you need also RAM for the OS - for the other ram it's equal if you use it for KVMs or CTs...

I would say an CT is quite secure - but you can do a lot IO inside the CT, which reduce the speed of other CTs noticable.

Very good IO-Performance
Only local storage (or NFS)
Access to other Filesystems with bind-mounts
No kernelmodules inside the CTs
