Changes:
Fixed as described in the bug.
* CreateVlanIpRangeCmd still accept account/domainId info
* if account owns:
- one Isolated network with source nat service enabled, use this network
- more than one Isolated network with source nat service enabled - error out
- none Isolated networks with source nat service enabled, create it only in
case when there is an Isolated network offering with Availability=Required and
source nat service enabled.
The routing table with two nics may be messed up, due to we sent same
router(gateway) information from different DHCP server, in order to specify
default gateway. E.g.
Network A: 192.168.1.0/24, gw 192.168.1.1
Network B: 192.168.2.0/24, gw 192.168.2.1
User VM: Nic 1 connect to network A, get ip 192.168.1.10; nic 2 connect to
network B, get ip 192.168.2.10.
Set network A as the default network of user VM.
Currently we would send this information to user VM through DHCP offer:
In network A: dhcp-option:router 192.168.1.1
In network B: dhcp-option:router 192.168.1.1
So both NIC in the guest VM would receive 192.168.1.1 as router(gateway).
But, in CentOS 5.6, dhclient-scripts try to tell if the gateway is reachable
for current subnet.
So when we try to enable nic 2(eth1) of user VM, dhclient would receive:
IP: 192.168.2.10
Mask: 255.255.255.0
Router: 192.168.1.1
Then it would found that the specified gateway(router) is not within its own
subnet(192.168.2.0/24). But since we send out this ip(192.168.1.1) as the
gateway for it, dhclient thought that it should got someway to access the
network through this IP. So it would execute:
ip route add 192.168.1.1 dev eth1
ip route replace default via 192.168.1.1 dev eth1
But it can never reach 192.168.1.1(which is in the eth0's subnet and the
gateway of eth0) by go through eth1 interface. So it is messed up.
We've tested Windows 2008 R2, CentOS 5.3, CentOS 5.6 and Ubuntu 10.04. Windows
and Ubuntu are fine with above policy.
To solve this, we send different dhcp:router option according to the guest OS
type now.
We may need expand this list later, but for now we only know that CentOS and
RHEL would behavior in this way.
status 14042: resolved fixed
Changes done:
- Provide UUID for userid and domainid only while constructing the login response. Session will hold the DB id's as before, to ensure other parts keep working.
- This reverts commit de28aa3ddde5b601f2f234f2eccef871fbaf1a06.
