Virtualization and E5200

[r9]

I have E5200 and does not support Intel® Virtualization Technology. I`v had installed vmware under Ubuntu and installed Vista as virtual server. But the lag was terrible. I would guess that is because E5200 is lacking those instructions. And I had trouble finding widows and linux version that would install on VMWARE. I was getting messages that my CPU is not 64 bit. Is this because of my CPU ?

 

[LittleLizard]

try virtualbox (i think thats how its called), is a good alternative software and may suit your needs

 

[Boyfriend]

E5200 don't have Intel VT. Still u can try Virtual PC 2007 SP1 (32, 64-Bit)or Virtual Box (cross platform, 32,64-Bit supported).
Increase RAM for virtual OS. That usually reduces the lag.

 

[r9]

My host OS was 64bit and the guest was 32bit is this OK ?
Also I read some where that in order to install 64bit guest than CPU must support Virtualization is this true ?

I don't know how to install a 64-bit guest OS. My CPU supports VT, and it is enabled and working, buy I get the same message about the CPU not supporting 64-bit when I try to install a 64-bit Guest OS.

I was giving 512 of ram. And it was saying that is using some 20-30 MHz CPU I could not change that.

If the host OS is 64Bit, you can either install 32Bit, or 64Bit guest OS

For 64Bit guest, there is no mandatory virtulization support.

it is your cpu. for one, it is slow and will have trouble running vista virtually. secondly, it doesnt have any of the instruction sets on it that make virtualization a smooth experience. so instead of programs like vmware directly using your hardware it uses software to emulate everything. obviously much slower.

To install 64Bit guest OS, your host must also be 64Bit, and 64Bit host OS can be installed only on 64Bit capable Processor+Mobo+BIOS, which are usually 64Bit by default now-a-days.

Are you saying that I`m would easy install 64bit guest instead of 32bit guest on 64 guest ?
That does make sense. What doesn`t is that I failed installing 64 bit guest and managed to install 32 guest. And as I said my CPU does not have VT support.

it all depends on the instruction sets on the cpu. generally the vm software you are using will tell you which it needs to run a 64bit guest.

Terrible!!! u give vista only 512MB RAM. At least specify 1GB (graphic + vista crapware(s)) to run it better. Vista (virtually any OS) can perform good without virtulization, because softwares emulate those necessary functions without much hassle. I have installed Windows 7 32 Bit guest OS under my 64 Bit Host Windows 7 for testing purpose.

I have also read some where that many of virtualizations programs recommend disabling this options. I think it was for AMD cpus that enabled Virtualization of the CPU could hurt the performance. I assume that this is because of lack of support by the software.

I have also installed Ubuntu as guest and that was lacking greatly.
I`m little confused about this Virtualization support. Many people say that is overrated.

If the lacking is because of the VT than what would be the cheapest Intel CPU that support this and why I could not install 64 guest under 64 host under VMWARE saying that I don`t have 64bit CPU ?

 

[Boyfriend]

it all depends on the instruction sets on the cpu. generally the vm software you are using will tell you which it needs to run a 64bit guest.

Modern CPUs have MMX, SSE, SSE2, SSE3, (SSSE3 by intel processors only), SSE4 (4.1,4.2) instructions sets. Virtulization software uses instructions up to SSE3 and can perform almost comparable with hardware VT. u will miss hardware VT only, when u run more than 1 guest OSes simultaneously, which normal home users don't do.

VT is not overrated. it lets the guest OS directly access your host CPU without using software. you can imagine this vastly increases performance.

Actually using hardware VT, ur guest OS can access ur computer resources directly without much depending on VT software and host OS. This increases speed, but negligibly. I will not recommend to upgrade ur processor. Just overclock it and increase ur host+guest RAM to get comparable speed.

sure if you only want to run one guest OS and you dont mind your guest OS running sluggish. hardware virtualization IS faster especially when running heavy software applications virtualized. we are also talking about using a linux OS to host a windows OS which is a lot slower than using a linux OS to host another linux OS.

That does make sense. What doesn`t is that I failed installing 64 bit guest and managed to install 32 guest. And as I said my CPU does not have VT support.

To install 64Bit host/guest, hardware VT is not mandatory. Only your processor, mobo, and bios should support it.
Have u ever consider that what is data width of ur RAM, Graphic card?? RAM should have 64Bit data width and graphic card(s) usually have 64, 128, 256, 384, 512 data width (multiple of 64). So all modern hardware is 64bit by design and should do well with 64bit host.

The thing is that I`m totally satisfied from the speed of my PC I`m running win7 x64 E5200@4.2GHz mem 933@ 4 4 4. I`m using multiple programs running while game minimized and I don`t have any slowdowns. But my Virtual machines are slow. Any explanation I could find it is the lacking of VT. And as you said VT is speeding vurtual machines but not by much.

as far as i know that is incorrect. you cannot run a 64bit guest OS without having 64bit hardware on the host machine AND the proper hardware VT on the host machine. you can only emulate 32bit operating systems if you do not have hardware VT.

I know that. I read somewhere that VT is needed in situation when we have 32bit host and want to install 64bit guest. Is this true ?

I don't deny the fact that hardware VT is beneficial. I want to clear that guest OS performance depends on software used for VT. Due to different kernal(s) and different code bases of Linux, how u can expect virtulization software will perform faster even with hardware VT, as nothing is well optimized for Linux, although most of time, things work stable. For better performance he will need Microsoft OS as host and then he can benefit well from hardware VT, else it is hit and try game.

i dont believe so. there is no reason to run a 64bit guest on a 32bit host.

perhaps. it is all complicated and a bit convoluted. as you said, it all depends on the host OS, the type of hardware being used and the hypervisor being used. i dont know if the OP specified this information exactly.
