I've noticed for some Solaris 10 x86 U2 diskless VMs seem to lose 25% of ICMP and other packets. The VMs are booted with the following grub configuration:
title Solaris_10 Network Single User Mode
kernel /I86PC.Solaris_10-1/multiboot kernel/unix -vs
module /I86PC.Solaris_10-1/x86.miniroot
The VMs lose packets for 30 seconds every 120 seconds.
Booting the same VM in, say, Linux, the issue does not occur
Anyone else seen anything like this?
