This is an ISSUE CAN”T setup PCI Device Resource Mappings, because of errors, e.g., “Configuration for iommugroup not correct (‘21’ != ‘’27)” thrown after Proxmox reboot!
Filter out network card udev information, e.g., enp1s0f1:
Add Virtual Network Adapters into Resource Mappings in Proxmox:
Add Mapped PCI Devices into Virtual Machine in Proxmox:
Virtual Network Cards can be set up as Network Cards, with hardware direct access, from a Network Cards pool (shared by other Virtual Machines), when the first Network Card is available.
This is the step by step guide, the fastest and easiest way install and run latest MacOS Sequoia 15.0.1 in VMware Workstation Pro on Windows 11.
Due to MacOS Sequoia has added detection whether OS is running in Virtual Machine, so it’s better install MacOS Sonoma at first, then upgrade to latest version MacOS Sequoia.
M. Change Max-OS Version (Currently 12) C. Change Catalog (Currently publicrelease) I. Only Print URLs (Currently Off) S. Set Current Catalog to SoftwareUpdate Catalog L. Clear SoftwareUpdate Catalog R. Toggle Recovery-Only (Currently Off) U. Show Catalog URL Q. Quit
Please select an option: 3
Downloading InstallAssistant.pkg for 062-78824 - 14.7 macOS Sonoma (23H124)...
DON’T enable Location Service during the installation! Otherwise, you can’t setup Time Zone, Date Time based on your area. You can login with your Apple ID during the installation.
Install VMware Tools
After MacOS installed and VM restarted, mount darwin.iso and install VMware Tools. Then Display Memory in MacOS becomes 128 MB, and support the Full Screen mode.
Upgrade MacOS
After MacOS Sonoma installed, make sure everything is OK, then copy the whole MacOS Sonoma directory to a new directory MacOS Sequoia (Upgraded). Open the new directory in VMware, and select I copied it, then you can upgrade MacOS to latest verion in System Settings -> Software Update.
By default, Ollama is only accessible from localhost. CORS error and HTTP 403 returned if try to invoke from other hosts.
To enable Ollama can be visited from hosts on intranet, run:
1
$ launchctl setenv OLLAMA_HOST "0.0.0.0"
in MacOS. Then restart Ollama. Then invoke it from hosts on intranet.
To enable Ollama can be visited from internet, with the help from ngrok, run:
