A system for monitoring a virtual machine executed on a host. The system includes a processor that receives an indication that a failure caused a storage device to be inaccessible to the virtual machine, the inaccessible storage device impacting an ability of the virtual machine to provide service, and applies a remedy to restore access to the storage device based on a type of the failure.

Protecting virtual machines against storage connectivity failures

A system for proactive resource reservation for protecting virtual machines. The system includes a cluster of hosts, wherein the cluster of hosts includes a master host, a first slave host, and one or more other slave hosts, and wherein the first slave host executes one or more virtual machines thereon. The first slave host is configured to identify a failure that impacts an ability of the one or more virtual machines to provide service, and calculate a list of impacted virtual machines. The master host is configured to receive a request to reserve resources on another host in the cluster of hosts to enable the impacted one or more virtual machines to failover, calculate a resource capacity among the cluster of hosts, determine whether the calculated resource capacity is sufficient to reserve the resources, and send an indication as to whether the resources are reserved.

Proactive resource reservation for protecting virtual machines

A system for monitoring virtual machines includes a master host and a slave host. The slave host includes a primary virtual machine and a secondary virtual machine. The slave host is configured to identify a failure that impacts an ability of at least one of the primary virtual machine and the secondary virtual machine to provide service. If the failure is a Permanent Device Loss failure, the slave host is configured to terminate each impacted virtual machine. If the failure is an All Paths Down failure, the master host is configured to apply one of the following: a first remedy if the primary virtual machine is impacted and the secondary virtual machine is not impacted; a second remedy if the secondary virtual machine is impacted and the primary virtual machine is not impacted; or a third remedy if both the primary virtual machine and the secondary virtual machine are impacted.
