VIOMB(4) - Device Drivers Manual # VIOMB(4) - Device Drivers Manual NAME # viomb - VirtIO memory ballooning driver SYNOPSIS # viomb* at virtio? DESCRIPTION # The viomb driver supports the virtio-compliant memory ballooning device. Memory ballooning works as follows: The host operator requests a guest to return some amount of memory to the host (via, for example, the QEMU monitor balloon command). The hypervisor sends the request via the VirtIO memory ballooning device. ...
VIORND(4) - Device Drivers Manual # VIORND(4) - Device Drivers Manual NAME # viornd - VirtIO random number device SYNOPSIS # viornd* at virtio? flags 0x00 DESCRIPTION # The viornd driver provides a virtual random number generator using a virtio(4) entropy device provided by QEMU 1.3 and later, and possibly by other hypervisors. As there is currently no way for viornd to determine how much entropy is needed, the second byte of the flags value can be used to configure how often it should request more entropy from the host. ...
