Lately, the builds have been failing due to an error raised from qemu-arm. For example, in commit 2763316cd. The default vm.mmap_min_addr setting on my RHEL7.4 machine is 4096=0x1000. Changing this setting exactly to 65536, allows qemu-arm to work. Configure networking (qemu-arm-virt) Networking under qemu may be somewhat tricky and specific configuration details may vary depending on the host configuration/distro/etc. Thus here there are some few suggestions to try having your set up ready as easy as possible. So, if you want to have networking on your virtualized guest then you can try:Install QEMU and the EFI image for QEMU: $ sudo apt-get install qemu-system-arm qemu-efi Now you'll need to create pflash volumes for UEFI. Two volumes are required, one static one for the UEFI firmware, and another dynamic one to store variables. Both need to be exactly 64M in size. While looking through guides online, I couldn't find much documentation on emulating ARM within QEMU let alone virt-manager, so I decided to make a quick gui... $ qemu-system-aarch64 -M virt -cpu max,pmu=off,sve=on,sve128=on,sve256=on The example above disables the PMU and enables the first two SVE vector lengths for the max CPU type. Note, the sve=on isn’t actually necessary, because, as we observed above with our probe of the max CPU type, sve is already on by default. This is a platform which doesn’t correspond to any real hardware and is designed for use in virtual machines. You’ll need to compile Linux with a suitable configuration for running on the virt board. virt supports PCI, virtio, recent CPUs and large amounts of RAM. It also supports 64-bit CPUs. Board-specific documentation ¶ A TPM device can be connected to the virt board by following the steps below.
