#7019 fixed poor performance when building the Solaris kernel peter.dennis@oracle.com
Description

Host Operating System: OpenSolaris - build snv_134a Guest: OpenSolaris - build snv_134a - with the guest additions installed Physical h/w: Sun Fire X4600 M2 (8 quad core AMD CPU), 65Gb memory

Issue: When building the Solaris kernel (ON) the performance of the Virtual Machine drops and the build ultimately fails. Upon initial investigation it would appear some I/O issue occurs.

The guest reports the following errors:

Jun 16 13:31:22 on-osol1005-bld-x scsi: [ID 107833 kern.warning] WARNING: /pci@0,0/pci-ide@1,1/ide@1 (ata1): Jun 16 13:31:22 on-osol1005-bld-x timeout: abort request, target=0 lun=0 Jun 16 13:31:22 on-osol1005-bld-x scsi: [ID 107833 kern.warning] WARNING: /pci@0,0/pci-ide@1,1/ide@1 (ata1): Jun 16 13:31:22 on-osol1005-bld-x timeout: abort device, target=0 lun=0 Jun 16 13:31:22 on-osol1005-bld-x scsi: [ID 107833 kern.warning] WARNING: /pci@0,0/pci-ide@1,1/ide@1 (ata1): Jun 16 13:31:22 on-osol1005-bld-x timeout: reset target, target=0 lun=0 Jun 16 13:31:22 on-osol1005-bld-x scsi: [ID 107833 kern.warning] WARNING: /pci@0,0/pci-ide@1,1/ide@1 (ata1): Jun 16 13:31:22 on-osol1005-bld-x timeout: reset bus, target=0 lun=0

and the VBox.log showed:

This issue has not been isolated to just this particular system - another build system - using the same software mix had the same issues.

The host was not busy at all.

I have marked this as major as this is essentially preventing the use of VB as tool to host build systems.

I have attached the following information:

o VBox.log o showvminfo o showhdinfo

Any information on what could be the problem or any diagnostics that can help track it down appreciated.

#11341 obsolete poor 2D-Video-Acceleration performance after update 4.2.4 => 4.2.6 bkgmjo
Description

When using 2D-Video acceleration on machines that used to work fine in scaled mode on VB 4.2.4 minutes ago the contents of the screen are now barely drawn.

The logon screen of Windows for example only shows some pixles of my typing, if any at all. Mouse cursor on integrated mode is barely visible. Going back to unscaled mode displays everything fine.

Also the CPU load even without 2D-Video acceleration on the host system during scaled mode is much higher in this version, maxing out 2 of my CPU cores on smallest screen changes.

I never checked this before on Version 4.2.4 but should 2D-Acceleration not use the hosts graphic hardware? It shows 0% Load on my GPU. Might be the problem here.

Changing the amount of virtual graphic memory does not seem to have any effect, same with the 3D-acceleration option. Also tried reinstalling everything without luck.

This is 100% reproducible with all my machines using as Guest Windows 7 or Windows XP.

System:

Phenom 2 955 x4 (4x 3.2 GHz)

12 GB DDR-3 Ram

Sapphire Radeon HD 4890 (850MHz/1GB GDDR-5)

Windows 7 x64

Have a happy new year!
