Ethernet losing Package VBOX 4.3.10 R93012

[Vinicius]

Hey guys,

I downloaded virtualBox 4.3.10 r93012

After setup a VM and start working on it as Bridge connection ( fixed IP ).

Did all setups and installed EBS ( Preparation environment for Project ), start working hard on environment my ethernet suddenly start losing Ethernet packages and affect my host as well, I tried many kind of configuration even reconfigured VM, but till now when I active Ethernet at my VM my connection became unstable and lose packages.

Please advise if someone already passed thru it or I'm the only luck one.

********************** EDIT ****************************
Installed at VM: Oracle Linux 6 ( 64bits ) 8GB Ram
Host: windows 7 ( 64bits ) 16Gb Ram
Guest Addon not installed.

thanks !

00:00:02.287681 Logical host processors: 8 present, 8 max, 8 online, online mask: 00000000000000ff

Two things here.
1) You are committing all of the cores to the guest which will lead to problems. VirtualBox does not deal with threads so set no more than 2 for the CPU count.
2) AFAIK this is still a know issue with network issues with SMP on certain Distros. Set it to one and see if the packets stop dropping.

If you want to continue I will need to see the following:

From the hosts terminal/command window type VBoxManage showvminfo <VM Name> --details and post here. Replace <VM Name> with the actual name of the VM. Use " " if the name has a space in it.

Note: if the host is Windows you need to be in the directory that has VBoxManage.exe for the command to work.

what is it?
2) AFAIK this is still a know issue with network issues with SMP on certain Distros. Set it to one and see if the packets stop dropping.

thanks a lot,
Vinicius

[Perryg]

You might try the VirtIO adapter and see if it performs better, and did you try setting the processor count to one?

As far as I know the network issues with more than one processor is still being worked on.

[Vinicius]

Yes I just did and keep losing packages.

[Perryg]

Then I have no more I can give you. I don't see these losses even with SMP so you might need to post a ticket at bugtracker

[Vinicius]

thanks for your help I'm quite done with all activities that I needed to do, so I'll not bother myself with it anymore.

[Vinicius]

I found the issue.

Virus..... first time I saw virus in Linux, but was my mistake, default passwords with 22 open to the world...

I'm back with 4 cores and no issue regarding packages.

thanks !

[Perryg]

Are you sure it was a virus or something planted? If it was a virus which one was it?

[loukingjr]

I would be interested to know as well.

[Vinicius]

there was many names.

But the principal was

sfewfesfsh
sfewfesfs

and my crontab was with lotsssss of lines and schedule wget to keep transfering scripts if I deleted, I took around 1h to be able to clean linux.

Basically this virus force stop of services every minute/ 5 minutes and so on...

thanks !

[loukingjr]

if understand correctly, this is actually a rootkit rather than a virus?

[Vinicius]

Correct !

VM working normally with 4 cores.
