#12906 obsolete 4.3.10 virtio bridged networking performance Chris Brown
Description

virtio with 4.3.10 is totally unusable. This is observed on all host types and different hardware configurations.

Simple Test case: Load an EL or OEL 6.x guest and configure it with a bridged virtio nic. Perform a simple network operation in the guest such making/removing a directory and some files on NFS v3 mounted filesystem in the guest.

EG:

mkdir foobar
time { for i in `seq 0 1000`; do echo foo > foobar/file_${i}; done }
time rm -rf foobar

#13217 obsolete 4.3.14 VirtualBox.exe Crashes after fresh install on Windows 7. Robw
Description

I updated to 4.3.14 after getting a popup saying a newer version of Virtual Box was available. I did the update but thereafter VirtualBox. Exe crashed.

I have tried for two days to do a fresh install but all to no avail.

I have 1 deleted .VirtualBox completely

  1. I have restored and tinkered vith VirtualBox.xml ( One time only I actually got it to come doing this but with an older version of VB)

I have tried several revisions of Virtual Box and get the same thing so I guess not version related. I always seem to get the same event reported.

Faulting application name: VirtualBox.exe, version: 0.0.0.0, time stamp: 0x53c537c5 Faulting module name: ntdll.dll, version: 6.1.7601.18247, time stamp: 0x521eaf24 Exception code: 0xc0000005 Fault offset: 0x00000000000508c5 Faulting process id: 0x1c50 Faulting application start time: 0x01cfa420debdcd1e Faulting application path: C:\Program Files\Oracle\VirtualBox\VirtualBox.exe Faulting module path: C:\Windows\SYSTEM32\ntdll.dll Report Id: 1c7f9da6-1014-11e4-bb63-7071bcb09765
