Description

Hi,

I'm noticing my network interfaces on my VM is very slow 300-400KB/s when using any of these network intefaces:

PCnet-PCI II (Am79C970A) PCnet-FAST III (Am79C973) Intel PRO/1000 MT Deesktop (82540EM) Intel PRO/1000 T Server (82543GC) Intel PRO/1000 MT Server (82545EM) - couldn't bring network up

When I used:

Paravirtualized Network (virtio-net)

I saw the normal speeds ie 3-4MB/s which is what I should be getting.

The virtual machine is a Debian 9 (Stretch)

Linux virtualmachine 4.9.0-7-amd64 #1 SMP Debian 4.9.110-1 (2018-07-05) x86_64 GNU/Linux

ii virtualbox-guest-dkms 5.2.10-dfsg-6~bpo9+1 all x86 virtualization solution - guest addition module source for dkms

ii virtualbox-guest-utils 5.2.10-dfsg-6~bpo9+1 amd64 x86 virtualization solution - non-X11 guest utilities ii virtualbox-guest-x11 5.2.10-dfsg-6~bpo9+1 amd64 x86 virtualization solution - X11 guest utilities

The host is Archlinux (latest updates 2018-07-20) ie:

Linux host 4.17.6-1-ARCH #1 SMP PREEMPT Wed Jul 11 19:14:29 UTC 2018 x86_64 GNU/Linux

The virtual machine currently has:

Base Memory: 2048MB Chipset: PIIX3 Enable I/O APIC = yes Proceessor(s) = 4 Execution Cap = 100% PAE/NX = false Paravirtulization Interface: Default VT-x/AMD-V = yes Nested Paging = yes Video Memory 128MB

Network:

Bridged Adaptor, on VLAN 2. (VLAN is set inside of the virtual machine). Has dual stack IPv4 & IPv6 ie NAT IPv6 addressss and IPv6 GLA address.

The version of VirtualBox that ArchLinux has at the moment is 5.2.16 r123745
