How many VM you will run on an 8 core, 32GB RAM node?
I would like to know some input from LET friends.
On average, how many VM you will run on a node
1).
- KVM
- 8 Core CPU with HT & VT
- 16 Threads
- Processor Base Frequency: 2.4 GHz
- RAM: 32GB ECC
2).
- OpenVZ
- 8 Core CPU with HT & VT
- 16 Threads
- Processor Base Frequency: 2.4 GHz
- RAM: 32GB ECC

Unlimited on both if done correctly. If not done correctly 1
Probably about the same as how many eggs can you get in one basket.
True, configuration part is very important.

What the OP probably means: how many VPSes would a typical provider put on these nodes? Granted, some LEB providers would be 200...those providing better service, maybe...30ish? All depends on plans of course but perhaps some people can share their ratios.
~20 2GB VPS servers.
Doubtful the better providers would share their ratios, no reason to clue in the less than better providers.
Scam detected. 20x2GB=40GB > 32GB.
Nearly everyone oversells RAM. With OVZ or KVM with KSM this is not a problem in general.
Your main limit will be IO so without you telling us what kind of hdd those servers will have it's hard to tell.
RAID 10?
Hardware RAID?
BBU?
100% SSD? SAS? SATA HDD?
etc

since it's a only 8 core CPU i would put no more than 8 without overselling

Welcome to low end box

Anxiously awaiting your plans. Can I order a 128MB VPS? What will be the pricing? Will it at least be cheaper than a 2 core Kimsufi dedicated server - €4.99? Will I also get 500GB disk, not oversold? By that I mean the I/O can't be oversold. I want to use 100% of I/O, so it would be best if you give me my own disk. Surely you will be able to give me some hefty discounts since I'm only ordering 128MB RAM. /s
Highly depends on the type of plans, what people are using them for, where they're advertised. Just the number of VMs doesn't signify better or worse service.
i am not the provider here you are. that was my personal opinion. if you oversell the fuck outta your servers does not really bother me.
Going with OpenVZ, I know nothing about KVM from a provider view sorry.
Assuming you are a host from your username selling VPS's to people who use them for the normal cheap and non-critical vps type stuff, and with 4x newish drives in hardware RAID 10 then i would say 100 with very few if any issues.
If you use OpenVZ's excellent limiting and configuration options, a very strict TOS and autokilling of intensive stuff then 200-300 would be fine. 300 was pushing it on the E3 GVH nodes, mostly due to lack of RAM and network congestion.
does not compute.
But GVH
LoL, like I say luv trolls
Please don't become a host!
OpenVZ.... probably wouldn't sell less than 128GB of memory and up to 10x the amount of storage.
That'd probably put you at somewhere around 20-30% of the resources actually used at any given moment. It's amazing how many people buy OpenVZ to let it idle.
1000. mtwiscool, a respected and knowledgeable industry provider managed this. https://vpsboard.com/topic/4219-i-want-to-provide-0361-per-year-vps39s/
I scanned all 5 pages of that thread waiting for the bit where he overcame all odds and supplied 1000s of 128mb accounts to all on his 32Gb machine for $1/yr. I seem to have missed the bit where it actually happened.
I think I read somewhere he managed a few hundred but IDK. Even a few hundred is an achievement on the hardware he was running but I guess the vast majority idled their boxes.
he said in the thread any abuse means termination. how can you use a "box" in such circumstances?
Possibly, but only if KSM is effective enough to trim 8GB plus however much the host OS needs to run the VM software.
Does Openstack have KSM flags?
