![]() QEMU - a generic, open source hardware emulator and virtualization suite.Virtualization - the concept and technique that permits running software in an environment separate from a computer operating system.Also, ACPI daemon sys-power/acpid should be installed and running on the guest. For this to work properly, ACPI functionality on the guest is necessary. ![]() Host control scripts may send a system_powerdown message to the virtual machine in order to shut it down. However, there are security concerns with this approach. A way to fix this is to enable the "VirtIO Random Number Generator support" (HW_RANDOM_VIRTIO=y) in the guest kernel and boot with the QEMU virtio-rng-pci device.Īnother way to solve this is to enable "Trust the CPU manufacturer to initialize Linux's CRNG" (RANDOM_TRUST_CPU=y) in the guest kernel. If the guest boots slow, or if the boot hangs on * Checking your configfile (/etc/syslog-ng/nf) or there are syslog messages like random: dbus-deamon: uninitialized urandom read (12 bytes read) or random: crng init done (12 seconds after booting), this is likely due to the lack of entropy.
