Abstract: Systems and methods are described herein for dynamic debug logging during application runtime. In an example, a wrapper can be added to the code for functions of the application. During runtime, the wrapper can cause the functions to retain certain debug data. In one example, a function call graph can be constructed, which can include all the possible function call paths for the application. When an error occurs, if the application does not have a stack trace tool or API available, the application can use the function call graph to determine all possible function call paths between the entrant function and the errored function. If an application does have a stack trace tool or API, then the application can retrieve the actual function call path that led to the error. The application can enable a debug flag in the wrapper for each function in the function call path, which can cause those functions to log runtime debug data.

Abstract: Methods and systems for balancing resources in a virtual machine computing environment are disclosed. A server can receive data illustrating the configuration of host machines and virtual machines in client computing environment. A simulated computing environment can be created that mirrors the configuration of the client computing environment. Data relating to resource usage (e.g., processor, memory, and storage) of the host machines can be received. The resource usage can be simulated in the simulated computing environment to mirror the usage of the client computing environment. A recommendation to execute a migration of a virtual machine can be received from the simulated computing environment. Instructions to execute a migration corresponding to the recommended migration can be generated and sent to the client computing environment.

Abstract: Techniques for automatic firewall configuration in a virtual network environment are described. In one example embodiment, firewall rules are configured using virtual machine (VM) inventory objects. The firewall rules are then transformed by replacing the VM inventory objects in the configured firewall rules with associated Internet protocol (IP) addresses using an IP address management table (IPAM) table and a network address translation (NAT) table. The transformed firewall rules are then sent to a firewall engine for filtering communication from and to VMs running on a first machine on one or more computing networks and communication from and to VMs running on a second machine on one or more computing networks at a firewall according to the transformed firewall rules.

Abstract: A system for a reservation for a multi-machine application can include a server virtualization engine configured to create a mixed reservation of information technology resources from a cluster of hosts including a virtual machine host and a container host. The system can include a cloud management engine configured to create a multi-machine blueprint from the mixed reservation including a virtual machine template, a container image, and a definition of networking. The cloud management engine can be configured to deploy the multi-machine blueprint to provide a multi-machine application.

Abstract: Techniques for dynamically configuring a dynamic host configuration protocol (DHCP) server in a virtual network environment are described. In one example embodiment, DHCP bindings are configured using virtual machine (VM) inventory objects. Further, the configured DHCP bindings are transformed by replacing the VM inventory objects in the configured DHCP bindings with associated media access control (MAC) addresses using a VM object attribute table. Furthermore, the transformed DHCP bindings are sent to the DHCP sever for assigning Internet protocol (IP) addresses to multiple VMs running on a plurality of host computing systems in a computing network.

Abstract: Techniques for dynamic configuration of a load balancer in a virtual network environment are described. In one example embodiment, load balancing rules are configured using virtual machine (VM) inventory objects. The configured load balancing rules are then transformed by replacing the VM inventory objects in the configured load balancing rules with associated Internet protocol (IP) addresses using an IP address management (IPAM) table or a network address translation (NAT) table. The transformed load balancing rules are then sent to the load balancer for load balancing network traffic between a plurality of VMs running on one or more host computing systems in one or more computing networks.

In one example embodiment, DNS rules are configured using virtual machine (VM) inventory objects and associated DNS names. Further, the configured DNS rules are transformed by replacing the VM inventory objects in the configured DNS rules with associated Internet protocol (IP) addresses using an IP address management (IPAM) table or a network address translation (NAT) table and the DNS names in the configured DNS rules with modified DNS names using a zone table and a view table. Furthermore, the transformed DNS rules are sent to the DNS server for performing domain name resolutions associated with multiple VMs running on a plurality of host computing systems in a computing network.
