Instalei o Virtual Box 4.2.4r81684
Até ontem de manhã estava tudo ok, porém desde ontem a noite, a máquina virtual está muito, muito, muito lenta.
O que eu devo configurar para melhorar o desempenho?

Post the guests log file (as an attachment)
See Online Users Manual for the location of the file.

I have the same problem since the upgrade.
I have a Lenovo W520 with XP Core 7i a Momentus XT 750 hdd.
Here is my log file.

Any help will be appreciated.

@iMVirtual,

First I would fix this. Something strange here. I would expect to see 64-bit as well.

What is the guest exactly?

00:00:40.552715     Host path 'D:\LapData\VMShareData', map name 'VMShareData', writable, automount=true, create_symlinks=false

I already Fix this is a leftover share, it didn't make any difference.

I believe that after updating to a new Virtualbox version, you should reinstall the Guest additions in each of your VMs.

If you read the log file you would see that the installed guest additions is 4.2.4

@iMVirtual,

What version did you upgrade from?

V 4.2.0

@iMVirtual: Reduce the number of cores assigned to the guest. 1 is probably plenty. 4 is definitely too much considering that it leaves none for the host. And since an VM services are actually performed by the host, leaving the host with no CPU results in... ah, you guessed.

I have 8 CPUs, and I was just trying some different configs to speed up the VM.

Your earlier message said you were using a Lenovo W520. My searches indicated that it has a quad core CPU.

i7 ?

So I guess quad core but if HyperThreading is enabled, they show up as 8 in windows.

It doesn't matter what they show up as. It's a quad core CPU, so leave one core for the host, assign a max of 3 cores to VMs. Try assigning one core per VM first, as that is what is known to work for the majority of users.
