Problems solved by technology
[0005] In the above implementation, each VM needs to install the HA tool. If the VM cannot install the HA tool because it uses a non-standard operating system, the VM detection / backup function cannot be realized.
When the HA tool can send heartbeat messages, it cannot guarantee that the VM can provide normal business applications. Therefore, the physical host cannot restart or reconfigure the VM in an accurate and timely manner, resulting in interruption of business applications.
In addition, the HA agent of each physical host can only send heartbeat messages in the control network, but cannot send heartbeat messages in the business network. Therefore, when the business network is abnormal, it cannot be resolved through the backup function of the physical host.

Embodiment Construction
[0043] Aiming at the problems existing in the prior art, Embodiment 1 of the present invention provides a virtual machine fault handling method, which is applied to an HA network including multiple physical hosts (that is, virtual platform-based HA technology), and each physical host There are VMs running (multiple VMs can be run), and multiple physical hosts join the same HA cluster. Further, among the multiple physical hosts, a virtual router (vRouter) runs on one of the physical hosts, and the NQA function is configured on the virtual router.
[0044] In the above application scenarios, such as figure 2 As shown, the method includes the following steps:
[0045] In step 201, the virtual router uses the NQA function to detect whether the VM is faulty; when the VM is faulty, the virtual router determines the fault type of the VM, and executes step 202; when the VM is not faulty, end the process, or loop detection. The fault type of the VM is an abnormal VM service or a net...

The present invention discloses a virtual machine failure processing method and device, the method comprising: a virtual router uses the NQA function to detect whether a VM fails; when the VM fails, the virtual router determines the failure type of the VM; The virtual router sends a fault notification message to the physical host; when the physical host determines that the VM is running on the physical host, it uses the fault type of the VM to perform fault processing on the VM. In the embodiment of the present invention, the VM does not need to install an HA tool, can quickly restore network connectivity, and can avoid service application interruption.
Description
technical field [0001] The present invention relates to the technical field of communications, and in particular to a virtual machine fault handling method and device. Background technique [0002] Virtualization technology means that computer components run on a virtual basis rather than on a real basis. Virtualization technology can expand hardware capacity and simplify the reconfiguration process of software. In the virtualization technology, the HA (High Availability, high availability) technology of the virtual platform is usually used to improve the reliability of the business application. Such as figure 1 As shown in the figure, it is a schematic diagram of networking of the HA technology of the virtual platform. The network includes multiple physical hosts, and multiple VMs (Virtual Machines, virtual machines) run on each physical host, and related business applications will be installed on the VMs, so as to provide users with various application services through t...
