Do Hyper-V guests see multiple CPUs (sockets) or multiple CPU cores when assigned more than 1 vCPU?

http://serverfault.com – I have SQL Server 2008 Express running on Hyper-V based virtual machine with two vCPU-s. I've just been reading up on SQL Server 2012 Express and noticed that it's CPU is "Limited to lesser of 1 Socket or 4 cores" (http://msdn.microsoft.com/en-us/library/cc645993(v=SQL.110).aspx) My question is how do the SQL Server 2012 limits on CPUs/Cores translate into vCPU-s? Are they "processors" or are they "cores"? EDIT: I've just found this: Are vCPU the same as 1 Socket, or a single Core? Basically the solution is download CPU-Z and check, which I did. On my 2 x vCPU VPS the CPUZ is showing 1 co (HowTos)

I had two of my CPUs lock up on one of my servers. From dmesg:

BUG: soft lockup - CPU#1 stuck for 23s! [vmx-vcpu-0:6148]

and later:

BUG: soft lockup - CPU#2 stuck for 23s! [vmx-vcpu-0:6148]

I'm trying to figure out why this would happen; the processor has 4 cores with hyperthreading, so the OS sees it as 8 cores.

VMWare/VirtualBox vCPU 23 weeks 3 days ago

If I install VMWare workstation or VirtualBox, it uses my REAL hardware. I know that there is a virtualization platform that can create vCPU (virtual CPU). I can tell the vCPU how much ghz to use from each of my cores.

Do you know if this is possible using VMWare/VirtualBox ? Or do I have to install a server version of any product ? Open Source is always preffered :-)

Thanks !

I have a server with an Intel Core i7 processor (4 cores). If I view processor activity in Task Manager I see that there are 8 cores.

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.

I have a Dell server with two cpus, each cpu has 6 cores, and each core is hyperthreaded (i.e. should be equivalent to two virtual cores).

I'm aware that SQL Server Express 2008 is having few limitations on the database size and the CPU utilization. In MSDN documentation it was mentioned on the express edition would use only one CPU. I went through the following links but I'm not clear about this: here and here

I have a quad core processor server.

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. This is licenced per core, and in a virtual hyperthreaded environment I think that core is a thread, not a full core.

I have an 8-core system (two quad-core Xeon processors) with 8 GB of memory running VMware ESXi 5.

I have 3 VMs currently running: 1 Debian VM using 1 vCPU, 1 WinXP VM using 2 vCPUs and my SQL Server VM.

Hi people! I'm having some problems with VMWare player networking. If someone could help me, i would be grateful. Everytime I start a VM, I get this erros menssage: could not connect to /dev/vmnet8 .
