network question (install and/or administration)

[noPa$$word]

I use a system with one onboard (motherboard) nic and two additional nics.

eth0 = 1000 MBit (on motherboard) is for administration
eth1 = 100 MBit Realtek Chipset (the same as eth2)
eth2 = 100 MBit Realtek Chipset (the same as eth1)

In proxmox/config/system I see

vmbr0 (eth0) with a static ip for administration ...
vmbr1 (eth1) none ip
vmbr2 (eth2) none ip

I use this proxmox for three ipcop-firewalls. vmbr1 and vmbr2 is for dem vms.

vmbr1 is for the wan-interface (red) and vmbr2 is for the lan-interface (green).

ask now:
If I create a new vm with two nic's (red / green), with network driver can I select?

Does the chipset drivers for the card fit?
If the card has 100 mbit, the driver may have 1000 mbit?
What makes the virtio drivers? Linux recognizes him?

can it be that a 1000 mbit driver for a 100 mbit card packet losses to lead?

thanks
k.w.

Hi,
the big advantage of virtualisation is the separation between real and virtual hardware. So you don't need use the same nics/driver. Take an e1000 and all is fine.

If the card has 100 mbit, the driver may have 1000 mbit?

It should be no problem to use a virt. 1000mbit-device. If you get rouble with the real nics: some people prefer intel-cards over realtek-cards.
