ASYNCHRONOUS MAPPING OF HOT-PLUGGED DEVICE ASSOCIATED WITH VIRTUAL MACHINE |
摘要 |
Systems and methods for asynchronous mapping of a hot-plugged I/O device associated with a virtual machine. An example method comprises: executing, by a first processing thread running on a host computer system, a virtual processor associated with a virtual machine; initializing, by a second processing thread, a table entry of a guest input/output (I/O) table associated with the virtual machine, wherein the table entry maps a device identifier of an I/O device to a memory buffer associated with the I/O device; pinning the memory buffer associated with the I/O device; responsive to receiving, by a hypervisor running on the host computer system, a completion signal from the second processing thread, notifying the virtual machine of the I/O device being hot-plugged. |

1. A method, comprising:
executing, by a first processing thread running on a host computer system, a virtual processor associated with a virtual machine; initializing, by a second processing thread, a table entry of a guest input/output (I/O) table associated with the virtual machine, wherein the table entry maps a device identifier of an I/O device to a memory buffer associated with the I/O device; pinning, by a processing device, the memory buffer associated with the I/O device; responsive to receiving, by a hypervisor running on the host computer system, a completion signal from the second processing thread, notifying the virtual machine of the I/O device being hot-plugged. |
