The problem was because in cloudstack when a vm is stopped it gets destroyed on the host. For a
windows vm the timeoffset (which can be set by changing the timezone from within the vm) is stored
in the platform:timeoffset attribute of vm record. The information is lost when the vm is destroted.
Made change to read and persist the platform:timeoffset vm attribute when an instance is stopped.
The value is persisted in the user_vm_details table. When the vm is started again the attribute is
set for the vm instance that gets created.
Currently it is very hard to see which tasks are pending in cloudstack
that need to be executed by xapi. Ideally we would like to have a
central overview of all tasks centrally. But for now being able to
enable tracelogging should give some insight in what is going on.
CLOUDSTACK-3042 - handle Scaling up of vm memory/CPU based on the presence of XS tools in the template
This also takes care of updation of VM after XS tools are installed in the vm and set memory values accordingly to support dynamic scaling after stop start of VM

During Scale up of VM, memory/cpu calculations should consider the memory/cpu overprovisioning factors which are set per cluster.

Currently XcpServerDiscoverer.java is only allowing till XenServer 6.1.0. Added
code to support XenServer 6.2.0. Also, added support to allow the RC build
of XenSever 6.2.0.

DevCloud is a XCP Kronos based xen. For this we use the XcpOssResource
whose memory limits were not set explicitly. Instead the base
CitrixResourceBase would set the limits. static_min was set to 128MB
failing the cpvm and ssvm start fails whose offerings have 100MB set to
the max limits.

When dmc is enabled allow cloudstack to scale the VM between dynamic
ranges. This requires a further commit where there is enough memory
available between dynamic-max and static-max for the VM to scale under
memory pressure. See the TODO in Xenserver56FP1Resource.java

23e54bb0 introduced multiple hypervisors support for cpu and memory
overcommit. Here the HypervisorGuru base which determines the min, max
range for the memory for all hypervisors computes the minCpu using the
MemoryOverCommit ratio and minMemory using the CpuOverCommit ratio.
Minor typo/logic issue but massive damage across all HV if enabled ;)

When setting memory constraints on Xen guests we should honor:
static-min <= dynamic-min <= dynamic-max <= static-max
Our VmSpec while allows the guests to like between dynamic-min and
dynamic-max the memory set by the resource set the static min to be
equal to the dynamic max. This restricts the hypervisor from ensuring
optimized memory handling of guests.
see: http://wiki.xen.org/wiki/XCP_FAQ_Dynamic_Memory_Control#How_does_XCP_choose_targets_for_guests_in_dynamic_range_mode.3F
Another fix was related the restrict_dmc option. when enabled (true)
this option disallows scaling a vm. The logic was reverse handled
allowing scaling when restrict_dmc was on. This control flow is now
fixed.

Missing default constructor fails the agent manager reloading the XCP
resource on reboot of management server. This is fixed by using the
default constructor as do other Xen resources and include a new resource
ala XenServers for XCP1.6.

Fixed by updating the patch files that has
entries to copy scipts on xenserver. Here we added
Add-To-VCPUs-Params-Live.sh
Added a check on Host params whether host restricts Dynamic memory control(DMC) to able to allow scale up VM.
If DMC is not enabled then static max and min are set to SO.

This feature enables adding of guest ip ranges (public ips) form different subnets.
In order to provide the dhcp service to a different subnet we create an ipalias on the router. This allows the router to listen to the dhcp request from the guest vms and respond accordingly. Every time a vm is deployed in the new subnet we configure an ip alias on the router. Cloudstack uses dnsmasq to provide dhcp service. We need to configure the dnsmasq to issue ips on the new subnets. Added a new class dnsmasqconfigurator which generates the dnsmasq confg file, this file replaces the old config in the router.
The details of the alias ips are stored in db in the nic_ip_alias table. Every time a new subnet is added one of the ip from the subnet is used to configure the ip alias.
I have pushed the code to https://github.com/bvbharatk/cloud-stack/tree/Cloudstack-702 , also rebased the code with master.
I need to test the code for advanced sg enabled network using kvm.
I have added the unit test
Marvin tests are at https://git-wip-us.apache.org/repos/asf?p=cloudstack.git;h=53e4965
Also accomodated some of the changes suggested by koushik.
corrected the import statements. renamed the IpAlias command to createIpAlias command.
This feature supports only ipv4
