Custom CPU models can specify any flag supported by QEMU/KVM, VM-specific flags must be from the following set for security reasons: pcid, spec-ctrl, ibpb, ssbd, virt-ssbd, amd-ssbd, amd-no-ssb, pdpe1gb, md-clear, hv-tlbflush, hv-evmcs, aesĭo not identify as a KVM virtual machine. Use +FLAG to enable, -FLAG to disable a flag. List of additional CPU flags separated by. Can be default or custom name (custom model names must be prefixed with custom-). We use the nocloud format for Linux, and configdrive2 for windows.Ĭloud-init: User name to change ssh keys and password for instead of the image’s configured default user.Ĭpu: ] Įmulated CPU type. The default depends on the configured operating system type ( ostype. Specifies the cloud-init configuration format. Also note that older cloud-init versions do not support hashed passwords. Specify a custom file containing all vendor data passed to the VM via cloud-init.Ĭloud-init: Password to assign the user. Specify a custom file containing all user data passed to the VM via cloud-init. Specify a custom file containing all network data passed to the VM via cloud-init. This is provider specific meaning configdrive2 and nocloud differ. Specify a custom file containing all meta data passed to the VM via" But, if only 4 would do work they could still get If all cores do the same heavy work they would all get 50% of a So, we set the cpulimit limit toĤ.0 (=400%). Should run at full load - as this would make the server so overloaded that Which would profit from having 8 vCPUs, but at no time all of those 8 cores Using a specific example: lets say we have a VM Processes in parallel, but the VM as a whole should not be able to run all This setting can be useful if a VM should have multiple vCPUs, as it runs a few In reality the usage may be even a bit higher as QemuĬan have additional threads for VM peripherals besides the vCPU core ones. If a VM with four cores utilizes all its cores fully it would Single process would fully use one single core it would have 100% CPU Time Time in percent, so 1.0 is equal to 100%, 2.5 to 250% and so on. It is a floating point value representing CPU With the cpulimit (“Host CPU Time”) option you can limit how much CPU time It is the same like kernel debugging of a normal Windows VM.In addition to the number of virtual cores, you can configure how much resourcesĪ VM can get in relation to the host CPU time and also in relation to other You create a pipe for the virtual com port. The Hyper-V also allows kernel debugging. now you can copy/rename/delete files in your reactos installation. When you shutdown the VM you can mount/unmount the virtual disk in your windows explorer. ReactOS will find a ACPI device but not a driver. let the installer install a bootloader in VBR, not in MBR. In the installer you create a big partition and format it with FAT. You should see the light blue background. Don't format it yet.Īdd the reactos-install-iso as cd/dvd image to the VM. Important: In the virtual disk don't create a volume or drive letter, yet. Add a virtual disk 'hdd1.vdh' with 1GB and MBR-partition style. Remove the netcard and the SCSI component from the new virtual PC. Make a link to desktop or start for easy use. Now on the start page, you will find 'Hyper-V manager'. On the left is: Windows features activate. In explorer, go to add/uninstall programs. Note: First of all, make sure you have read Installing ReactOS article.įirst you have to add Hyper-V to your Windows installation.
