Package: xen-utils-common Version: 4.0.0-1 Severity: normal When a qemu hvm with vif=['type=ioemu,bridge=eth0'] is created, xen will successfully create the required vif and tap bridge interfaces, but will create the corresponding iptables filter rules for the vif interface only, not the tap interface. With a FORWARD policy of DROP (e.g. by enabling antispoofing) network traffic from/to the hvm will fail.
As a quick fix, I added iptables -I FORWARD -m physdev --physdev-in $1 -j ACCEPT iptables -I FORWARD -m state --state RELATED,ESTABLISHED -m physdev --physdev-out $1 -j ACCEPT to /etc/xen/scripts/qemu-ifup, which makes the hvm networking functional, but the tap iptables filter rules won't get cleaned up when the hvm is shut down. -- System Information: Debian Release: 6.0 APT prefers squeeze-updates APT policy: (500, 'squeeze-updates'), (500, 'stable') Architecture: amd64 (x86_64) Kernel: Linux 2.6.32-5-xen-amd64 (SMP w/2 CPU cores) Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Versions of packages xen-utils-common depends on: ii gawk 1:3.1.7.dfsg-5 GNU awk, a pattern scanning and pr ii lsb-base 3.2-23.2squeeze1 Linux Standard Base 3.2 init scrip ii udev 164-3 /dev/ and hotplug management daemo ii xenstore-utils 4.0.1-2 Xenstore utilities for Xen xen-utils-common recommends no packages. xen-utils-common suggests no packages. -- Configuration Files: /etc/xen/scripts/qemu-ifup changed [not included] -- no debconf information -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
