root cause:
when vmsync reports system VM is down, CCP doesn't release the VM resource before starting it.
fix:
make sure cleanup is called for a VM when it is reported as Stopped
Unnecessary exception in MS logs while removing default NIC from VM. Following changes are made:
1. Changed the exception from CloudRuntimeException to InvalidParameterValueExecption.
2. Moved out validation logic to UserVMManagerImpl from VirtualMachineManagerImpl.
3. Handling InvalidParameterValueException from async API calls so that they are not logged as ERROR in MS logs.
requires storage migration resulting in failure of VM migration. This also improves
the hostsformigration api. Firstly we were trying to list all hosts and then
finding suitable storage pools for all volumes and then we were checking whether
vm migration requires storage migration to that host. Now the process is updated.
We are checking for only those volumes which are not in zone wide primary store.
We are verifying by comparing volumes->poolid->clusterid to host clusterid. If it
uses local or clusterids are different then verifying whether host has suitable
storage pools for the volume of the vm to be migrated too.
Changes:
PodId in which the router should get started was not being saved to the DB due to the VO's setter method not following the setXXX format. So when planner loaded the router from DB, it always got podId as null and that would allow planner to deploy the router in any pod. If the router happens to start in a different pod than the user VM, the Vm fails to start since the Dhcp service check fails.
Fixed the VO's setPodId method, that was causing the DB save operation fail.
Added a new flag 'checkBeforeCleanup' to StopCommand based on which check is done to see if VM is running in HV host.
If VM is running then in this case it is not stopped and the operation bails out.
Also modified the MS code to call the StopCommand with appropriate value for the flag based on the context.
Currently it is only set to 'true' when called from the new vmsync logic based on powerstate of VM. For rest it
is set to 'false' meaning no change in behaviour.
CLOUDSTACK-4762 : Enabling VGPU support for XenServer.
This feature is to enable the GPU-passthrough and vGPU functionality,
with the help of this feature, admins/users will be able to leverage
the GPU graphics unit power by deploying a virtul machine with GPU or
vGPU support or by changing the service offering of an existing VM
at any later point of time. There GPU/vGPU enabled VMs are able to run
graphical applications.
For now, this feature is only supported with XenServer hypervisor but
can be extended to add the support of other hypervisors.
