I already looked at this thread: Hyper-V and Hyper-threading: On or off?, but the only answer is Windows specific....
I am building a VM server (using Proxmox VE if that makes a difference) and was wondering about how hyper threading can affect virtual machines...
Specifically, if I max out the number of virtual machines, would hyper threading help, or hurt performance?
Also, the largest virtua
I was looking around on Wikipedia, and ran across the UltraSPARC T2 processor. This is a processor with 8 cores (8 physical processors) and 8 threads per core (64 logical processors!)
I'm aware of Intel's Hyper-Threading and other technologies, and I know collisions between the threads have the possibility of decreasing the processor's throughput.
One of our client's has an existing SCOM 2007 installation, with monitoring agents pushed out to all the Windows servers in their environment.
this question is regarding Netmap for Linux by Luigi Rizzo.
I have a server with 16 cores, but hyper-threaded, so it's 32 cores to the machine. If I remove hyper-threading, then I can open many instances of Netmap. But if hyper-threading is enabled (which I desire), I can open 2 instances of Netmap without any issue. Once I open a 3rd one, I receive an OOPS.
I have just got a Pentium D 820 to replace me old P4. The pentium D is a 2.8GHz CPU. However in BIOS and CPUZ on windows it is showing a single core Pentium 4 running at 2.8GHz with hyper threading.
In linux is is showing as 2 pentium 4 cpus at 2.8GHz but I don't know whether these are the 2 logical cores from hyperthreading or two real ones.

Can you help me with my software licensing issue?
I've seen lots of people saying we should turn hyperthreading on on hyper-v hosts, but I've got a dilemma.
We're going to be running SQL Server 2012 Enterprise on a 2012 hyper-V cluster.

We're going to be running SQL Server 2012 Enterprise on a 2012 hyper-V cluster. This is licenced per core, and in a virtual hyperthreaded environment I think that core is a thread, not a full core.
We have a number of Server 2012 systems, all of which run virtualised on Hyper-V 2012 server. We are having problems with two such virtual instances, both of which are used as file servers, whereby they occasionally stop responding to requests to serve files to clients.
I’m having several Windows Servers 2008 R2 which I previously accessed using Hyper-V Manager from Windows 7. On upgrading to Windows 8 and enabling the feature Hyper-V, this is no longer possible.
