Rohit Yadav created CLOUDSTACK-7340:
---------------------------------------
Summary: Instances unable to reach internet using SG provider and
KVM
Key: CLOUDSTACK-7340
URL: https://issues.apache.org/jira/browse/CLOUDSTACK-7340
Project: CloudStack
Issue Type: Bug
Security Level: Public (Anyone can view this level - this is the default.)
Affects Versions: 4.4.0, 4.5.0, 4.4.1
Reporter: Rohit Yadav
Priority: Blocker
Fix For: 4.4.1
Deployed a basic zone with Security Group, used KVM and setup agent.
Host: Ubuntu 14.04, Core i7,
The test hardware had two nics but used only eth0 and created two bridges
cloud0 and cloud1:
auto eth0
iface eth0 inet manual
auto wlan0
iface wlan0 inet manual
# Public network
auto cloudbr0
iface cloudbr0 inet static
address 192.168.1.150
netmask 255.255.255.0
gateway 192.168.1.1
dns-nameservers 192.168.1.1 8.8.8.8
#post-up route add default gw 192.168.1.1
bridge_ports eth0
bridge_fd 5
bridge_stp off
bridge_maxwait 1
# Private network
auto cloudbr1
iface cloudbr1 inet manual
bridge_ports none
bridge_fd 5
bridge_stp off
bridge_maxwait 1
The cloudstack-agent (4.4.1) was configured to use cloudbr0 for public, private
and guest network in its properties file. The default gateway was setup to
192.168.1.1 on cloudbr0 interface.
- SSVM was able to reach internet.
- CPVM was not
Bridge output:
$ brctl show
bridge name bridge id STP enabled interfaces
cloud0 8000.fe00a9fe0190 no vnet0
vnet4
vnet8
cloudbr0 8000.00012e4fde1c no eth0
vnet1
vnet2
vnet3
vnet5
vnet6
vnet7
vnet9
cloudbr1 8000.000000000000 no
lxcbr0 8000.000000000000 no
virbr0 8000.000000000000 yes
I'm suspecting something with traffic not going to right nic, not good at
debugging network/bridge/kvm stuff so I'll need someone to setup and try with
4.4 branch.
