Hyperd Configuration

Configuration file

The configuration file of Hyper is located under /etc/hyper/config by default. The file is in INI format：

# Root directory for hyperd
# Root=/var/lib/hyper/

# Specify the hypervisor: libvirt, qemu, qemu-kvm, kvm, xen, xenpv, kvmtool
# "kvm"  is equivalent to "qemu-kvm" which uses qemu with kvm acceleration.
# "qemu" is equivalent to "qemu-kvm" when the system enables kvm, otherwise
#        the hypervisor is "qemu-tcg" (qemu without kvm acceleration).
# When Hypervisor is not set, the hyperd will try to probe "qemu-kvm" or "xen"
# as the containers' hypervisor according to the host, if the host doesn't
# support any hardware-assisted technology, it will use "qemu-tcg".
#
# Hypervisor=qemu

# Boot kernel
Kernel=/var/lib/hyper/kernel

# Boot initrd
Initrd=/var/lib/hyper/hyper-initrd.img

# Storage driver for hyperd, valid value includes devicemapper, overlay, rawblock, and aufs
# StorageDriver=overlay

# Bridge device for hyperd, default is hyper0
# Bridge=

# Bridge ip address for the bridge device
# BridgeIP=

# If the host IP is provided, a TCP port will be listened for, same as the '--host' option
# Host=

# This is only useful for hypernetes, to disable the iptables setup by hyperd
# DisableIptables=false

# Enable vsock support. This only works with libvirt/qemu hypervisor and template disabled
# EnableVsock=false

# VmFactoryPolicy defines the policies to create factories
# VmFactoryPolicy = [FactoryConfig,]*FactoryConfig
# FactoryConfig   = {["cache":NUMBER,]["template":(true|false),]"cpu":NUMBER,"memory":NUMBER}
# Examples:
# VmFactoryPolicy={"cache":10, "cpu":1, "memory":128}
# VmFactoryPolicy={"cpu":3, "memory":1024}
# VmFactoryPolicy={"template":true, "cpu":1, "memory":128}
# VmFactoryPolicy={"cache":1, "template":true, "cpu":1, "memory":128}
# VmFactoryPolicy={"cache":10, "template":true, "cpu":1, "memory":128},{"template":true, "cpu":3, "memory":1024}
# It is recommended to specify the "cache" when VmFactoryPolicy is set,
# otherwise it is a less efficient factory
VmFactoryPolicy=
