Need SolusVM Help
Today, after around 3 weeks of waiting, I finally get my dedicated server (Intel 2x L5420, 8Gb EEC RAM). I install SolusVM on the server, and everything goes well, until I create a VM.
The VM refused to work, no matter what template, how I restarted it. I rebooted the server, and created a new VM, and it started to work. Yay.
I then proceeded to download OpenVZ templetes of the OpenVZ site. When I try to run these templates, the server REFUSES to start.
Can anybody help me? (I'm even willing to give admin details if somebody is that awesome!)

I manually started this via SSH:
dding IP address(es): 205.134.xxx.xx 205.134.xxx.xx
Setting CPU limit: 400
Setting CPU units: 1000
Setting CPUs: 4
Unable to start init, probably incorrect template
Container start failed
Stopping container ...
Container was stopped
Can't umount /vz/root/101: Device or resource busy
That's weird. I got these directly of the OpenVZ wiki.
are you sure you're on the right kernel?

I am running SolusVM on CentOS release 6.2, 64-bit.
I set all of the x64 templates as x64, and not as i386.
I think he means did you boot into the OpenVZ kernel (uname -a).
Linux 191.cheetahhost.net 2.6.32-042stab049.6 #1 SMP Mon Feb 6 19:16:12 MSK 2012 i686 i686 i386 GNU/Linux
Ahhhh. Er, how do we switch kernels?
You are using a 32 bit kernel....
Gah, did my host REALLY install a 32-bit kernel when I told them to install a 64-bit one.
@lele0108 you want to post your grub.conf here?
Word of warning, if you're planning to sell any plans on these nodes, watch out for the .32 kernels
Seriously consider RHEL 5 if you aren't using it for personal dev.
Francisco
@francisco what bad experience you had with.32 kernels?
For a lack of a nicer way of saying it, it's unstable as fuck.
Most nodes we put on it will go a couple days before it dead locks.
Check the OpenVZ bugzilla to see all of the reports of softlocks/deadlocks/panic's on .32's.
We tried to roll .32 and it was just a bad idea. We do .18's for now.
Francisco
Mmmmm I only have 3 nodes with openvz so maybe they aren't statistically relevant, but so far they are very stable (some weeks running) . Did you see the deadlock after some load pattern or it was random?
100% random. We got a few nodes (like 6) still on it that are stable, but most took a dive within a month. If we were OK with 30 day uptimes it'd be fine, but we're, including the clients, used to .18's 100 - 200+ day uptimes.
Francisco
Thanks for the heads up, I already talked to my host about switching my back to 64bit, didn't know why they provisioned me with 32. I am not selling this server, its for personal use :P
Thanks for the help, but I think I figured it out.
ok, so I should cross fingers:
10:13:20 up 25 days, 17:41
That's what I'm wondering, haha; we just released OVZ's on a .32 as well.
Depends how you use it
It's a backup node, so only vsftpd, rsync and dropbear are running in 99% of the containers. No vSwap. No VPN's. With typical use is where @Francisco is running into troubles, so YMMV
you named them all
the nodes are in full production, one of the three (the first I installed 25 days ago) is near the limit of VPS I planned to stock on the servers for now...

I think to have found a pattern at least with softlock. Today a guy in the forum reported a dd test with very low performances. I checked and noticed I forgot to lower vm swappiness, which usually I set at a value of 1. While I was at it I checked the other servers and since on one I've a test vps on this server I set swappiness=0 to see if I could see some difference, after one minute load spiked out and I was flooded with softlock messages. Just setting it again to 1 stopped the mess and everithing went back to normal...
