Description

Host and guest both are Windows XP

  1. Copied some text to the clipboard on the guest OS.

#4062 fixed host OS cpu always is above 50% yup
Description

I have linux debian squeeze as host os cpu: amd64 dc mem: 4gb

virtualbox-2.2.2-46594_Debian_lenny from http://download.virtualbox.org/virtualbox/debian (not virtualbox-ose)

(same problem was with virtualbox-ose from debian repo)

I have installed windows 2003 server as guest os ( ram 512mb, video 8mb, acpi on, vt on, 1 network interface). Is works fine.

host's (linux) cpu load is near 2-3% while guest os idle. If I start few programs ( openoffice, drweb, winrar, etc ...) cpu load of host (linux) jums to ~100% and when programs started it returns to 2-3%

cpu load of guest (windows) also falls to 0-1%

Problem:
there is a program named QIP - alternative icq client (http://download.qip.ru/qip8092.zip)

when I run this (installed) program on guest OS (windows) I get above 50% of cpu load on my host OS (linux) and 0-1% on guest OS (windows), the same thing if I run some more programs (openoffice etc.) but when I close qip, load gets to normal (2-3%) on host OS

maybe this is qip specific but why guest OS does not show great cpu load or maybe this is virtualbox hardware specific

when I start other guest box (winxp) both guests do not get more than 5% of cpu on host OS (linux) when i close that second guest (winxp) cpu load return to above 50% on host OS

same thing happens when qip runs on winxp

#12747 obsolete host Fedora 20 guest Fedora 20 VINF_EM_TRIPLE_FAULT crash at startup pascalc
Description

Hi, I just installed VirtualBox 4.3.8, and I have the same issues that I had with 4.3.6. The host is a Fedora 20 with kernel 3.13.4-200.fc20.x86_64; same for the guest.

If I disable nested paging, the guest is ok, though I must retry several times just after disabling nested paging (the VM freezes); After that, the VM works flawless (but it is slow)

It is the same for 2 other guests (64 bits) : Centos 5.7 and Ubuntu 13.10.

ArchLinux (i686) is working flawless, with or without nested paging.

Regards,
