chromium downloader for MacOS 10.8.5

If you happen to have MacBookPro3,1 with Intel Core 2 Duo 2.2Hz DDR2 SDRAM with MacOS 10.8.5 on board then you probably wonder if there is a chance to access internet with modern browser. Yes, now you can with chromium downloader for chromium-legacy.

However there are reported some issues with NVIDIA GeForce 8600M GT 128MB GPU and I can confirm it also. If you download the latest, as for now 121, Chromium will be installed but no visible window content could be seen. Instead I downloaded stable 114 version which run just fine. Probably you could run more recent version but put some additional settings regarding GPU.

Few words about Chromium 114 itself. It run just fine, but it makes MacBook struggle a little bit, it gets extremely hot. I even wonder if it would get on fire 🙂

Seperate Proxmox node from cluster

In order to separate Proxmox node from cluster:

systemctl stop pve-cluster
systemctl stop corosync
pmxcfs -l
rm /etc/pve/corosync.conf
rm -r /etc/corosync/*
killall pmxcfs
systemctl start pve-cluster
pvecm expected 1
rm /var/lib/corosync/*

Nested virtualization on Proxmox 7.4

If you would like to run virtual machine inside another virtual machine, then you need to have CPU with nested virtualization feature and this feature needs to be enabled. Even if enabled:

cat /sys/module/kvm_intel/parameters/nested  # Intel
cat /sys/module/kvm_amd/parameters/nested    # AMD

you might still have error on enabling virtualization inside virtual machine:

sudo modprobe kvm_intel
modprobe: ERROR: could not insert 'kvm_intel': Operation not supported

Still, even with “KVM hardware virtualization” set to Yes on VM Options pane in Proxmox UI, you may have trouble to get it to work. In case of Intel Xeon Gold 5412U there are no additional CPU flags available to set from Proxmox UI.

You need to select CPU type as “host” either from UI or inside VM configuration file (/etc/pve/qemu-server/XXX.conf). With this setting you get nearly all the features available and possible to pass from the host to guests.
