Sheng Yang 7e2fe6b6c9 Redundant Router: Fix isVmAlive() 2011-06-09 15:41:12 -07:00
Sheng Yang 62ac899091 bug 9154: Initial check in for enabling redundant virtual router 
This patch enable redundant virtual routers.

1. To enable this feature, db need to be updated using follow SQL by now(we
would get a UI way later):

UPDATE network_offerings SET redundant_router=1 WHERE guest_type="Virtual" AND
system_only=0;

2. System would try to start up two routers at different hosts. But if there is
only one host in the zone, system would start up two routers on it.

3. The failover part is using keepalived, and connection tracking part is using
conntrackd. There would be one master router and one backup router. The status
of router(master or backup) can be query from the database table domain_router
now. Management server would update the status every 30s by default.

4. The routers for the same zone would use same external NIC(same ip and mac).
The script used for fail-over would ensure only one external NIC present in the
network at any time.

5. Currently management server don't got the ability to stop one of router is
both of them reported as master. The feature is in the todo list.

After two routers start up, disconnect anyone of them, the guest network
shouldn't be affected, and established connection(http, ssh, etc.) should still
works. The fail-over on gateway part should be 3~4 seconds.

Currently the patch works with KVM. Would deal with vmware and XenServer soon.

prachi c2824edc03 Bug 9446: Investigator reports that a system vm is down even if it isn't.... 
Changes:
- Added new Investigator 'ManagementIPSystemVMInvestigator' that checks if Vm is alive only for System VM's that have a management IP address.
- If no management IP is found, ping test cannot be done, so this investigator would return null in that case.
- Current implementation InvestigatorImpl is renamed as 'UserVmDomRInvestigator' and does the ping test for user VMs only.
- Corrected the ping test code that was checking a hard-coded string. Now if the ping answer is negative, we just return null
- Added the new investigator to components.xml

prachi 53f8ebf6f0 Bug 9043 - VM manual migration - when destination host is out of memory for migration, VMs being migrated remained in 'migrating' state 
Changes:
- When migration fails we try to do cleanup on the destination host agent. The AgentUnavailableException in this cleanup was not caught.
-Due to that other cleanup like reverting capacity allocated and vm state were skipped.
-Fix is to catch the AgentUnavailableException so that rest of the cleanup can happen.
- Also corrected the exceptions in various cases of migration failure.
- In case the VM is still starting, HA should schedule a retry. Introduced a special migration exception for handling this.
