Guest Windows starvation and halt

[Technologov]

Windows XP Guest can be easily starved, and put to total halt, by massive networking exchange.

to reproduce:

1. Setup Windows XP host and guest

2. Download IP traffic generator:

3. enable host-networking.

4. Run CommTest (either direction)

5. Guest Windows will be halted, probably because I/O overload, until you stop this test manually (from host).

This bug might be, or be not, connected to bug #21.

Software: Windows XP Pro SP2 Eng, no extra patches, VirtualBox 1.3.6 Full.

I'm not convinced that this is a bug. Does the same happen with VMWare?

[Technologov]

a) try to reproduce my steps

b) It does not happens with Virtual PC

I think this problem is related to network-intensive application. For example, when I fire up my Windows XP virtual machine on Kubuntu 7.04, CPU usage looks good. However, when I tried to fire application such as web folders or download managers, host CPU usage hits 100%. Those programs work flawlessly in real(not virtual) windows.

Please reopen this bug if this is still relevant with VirtualBox 2.0.6.
