Something very useful - find the name of the virtual NIC on the host, and run a magical tc command: # ip l | grep vnet 47: vnet1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc htb master virbr0 state UNKNOWN mode DEFAULT group default qlen 1000 # tc class change dev vnet1 classid 1:1 root htb rate 100Mbit Here is an example of me using it to choke Steam:

I have an NVMe device that I use to passthrough to a virtual machine on Linux. It has some internal issue, a workaround that worked for me so far was described here: <hostdev mode="subsystem" type="pci" managed="yes"> <source> <address domain="0x0000" bus="0x6f" slot="0x00" function="0x0"/> </source> <boot order="1"/> <alias name="ua-sm2262"/> <address type="pci" domain="0x0000" bus="0x00" slot="0x07" function="0x0"/> </hostdev> <qemu:commandline> <qemu:arg value="-set"/> <qemu:arg value="device.ua-sm2262.x-msix-relocation=bar2"/> </qemu:commandline> Since some release of qemu it seems to no longer work and give an error message like this:...

For me this was the only way to stay learning, because just doing “exercises” makes no sense to my brain as there is no music produced that is remotely pleasurable to hear. With the tabs you instead can already mimic your favorite tunes - all that is required is some technical work to make your fingers accustomed to the changes in chord shapes....

I have an Arch (Gnome) on one physical disk and Ubuntu on another. At some point I decided to encrypt the Ubuntu installation. Ubuntu was just sitting on a simple /dev/nvme1n1p1 partition. I added a separate boot /dev/nvme1n1p2 device to keep grub on, and it had its benefits too. Main bootloader lives on the Arch disk. I followed the steps on Arch wiki, but during the boot there was no prompt to put password for decryption....
