Hello everyone!

I have two vms A and B, A is in vlan1 and B is in vlan2, how to share files between A and B? Or is there a way that a vm(C) can both access A and B? How to configure it? Suppose A, B and C are in different compute node. Appricate for your answer! Thanks!

这种情况我遇到过很多,我觉得最可能就是1,网络配置不正确;2,内存不够。不过你还是查查日志文件吧。

2014-08-31 07:12:47 -0500 asked a question Can not ping VM's floating ip

I am a fresh man in openstack, I install openstack using devstack in a server(192.168.4.185), when use the default configuration, that is FlatDHCP mode, it works well. But now i need to change the network mode to Vlan, and I've created two vms, one with fixed ip10.0.151.3, the other with fixed ip 10.0.151.4 and floating ip 192.168.4.160. Two vms can ping each other, but I can't ping 192.168.4.160. Could someone give me some advice? Thanks in advance! Here is part of my nova.conf:

[DEFAULT]
flat_interface = eth0
flat_network_bridge = br100
vlan_interface = eth1
public_interface = eth0
network_manager = nova.network.manager.VlanManager

Here is my /etc/network/interface:

auto lo
iface lo inet loopback

auto eth0
iface eth0 inet static
address 192.168.4.185
netmask 255.255.255.0
gateway 192.168.4.1
dns-nameservers 124.16.136.254

auto eth1
iface eth1 inet manual
up ifconfig eth1 up

Thanks, you can keep floating IP the same or change it during changing the vlan.Whatever.
