[Xen-devel] xen-4.1.3-rc1-pre changeset 23224:cccd6c68e1b9 hvm xl not execute vif-bridge when xl destroy hvmdomain or xl trigger hvmdomain power

[Teck Choon Giam <giamteckchoon@xxxxxxxxx>]

Hi,

I need to check whether is this intended?  When using xl create hvm
domains, it does execute vif-bridge script.  However, when doing xl
destroy or xl trigger hvmdomain power it doesn't execute vif-bridge
script.  I just did the following to test:

# cp -pvf /etc/xen/scripts/vif-bridge /etc/xen/scripts/vif-bridge.orig
# cat > /etc/xen/scripts/vif-bridge <<'EOF'
#!/bin/bash
echo "$@" >> vif-bridge.log
/etc/xen/scripts/vif-bridge.orig "$@"
EOF

When using xm and xl to create hvmdomain, I can see vif-bridge.log
appended with:

online type_if=vif
online type_if=vif
add type_if=tap
add type_if=tap

Since I have allocated 2 vifs (one for WAN and one for LAN)... so it
gets to execute vif-bridge once for each vif which looks right.

Now the problem is xl trigger hvmdomain power and xl destroy power.
Both never call vif-bridge script as there isn't any such line like:

offline type_if=vif
offline type_if=vif

Whereby when I tried with xm trigger hvmdomain power, it does call
vif-bridge script as the above two lines get logged.

This will leave the iptables FORWARD rule intact when using xl which I
reported before :(

Thanks.

Kindest regards,
