When running Linux in a VM, if I close the lid of my macbook, when I reopen it, for exemple, two hours later, the Linux VM time has "drifted" and is two hours in the past. https://developer.apple.com/documentation/virtualization/running_linux_in_a_virtual_machine Microsoft solves this issue on their Hypervisor with a RTC device /dev/ptp_hyperv, and configuring chrony to use it, see https://learn.microsoft.com/en-us/azure/virtual-machines/linux/time-sync#chrony Linux KVM do the same : https://docs.redhat.com/en/documentation/red_hat_enterprise_linux/7/html/virtualization_deployment_and_administration_guide/chap-kvm_guest_timing_management#sect-KVM_guest_timing_management-Host-guest-time-sync It seems there is also a virtio_rtc module coming Virtualizing macOS on macOS has AppleVirtualPlatformRTCPlugin setting time on the guest. But how to get a Linux time in sync with

The documentation is clear, https://developer.apple.com/documentation/vmnet "Packets sent from a different IPv4 address are dropped by the system." But I wanted to have some proxmox nodes (debian with lxc containers) to test and learn high-availability clustering with it Also it could be cool to use some containers for "micro-services" web architecture I'm using https://github.com/gyf304/vmcli to create the virtual machines (both x86/arm 64bits are usable), but due to this "single IP" limitation, I can't make a virtual hosts communicate Is there any option / configuration on bridge100 interface to bypass this limitation ?
