VBox 6.1.19 I have four Arch virtual machines, two with Ext4 and two with ZFS. All work fine with GA 6.1.16. The ZFS machines will not boot with GA's 6.1.18. I have one Ununtu 21.04 V machine running ZFS and it works fine. The problem only exists with Arch machines I installed VBox 6.1.19. Same problem. ZFS machines work fine when I go back to GA 6.1.16 I have tried GA 6.1.19 (142299), and GA 6.1.19(142514). No change. I attach log files of an Arch machine running GA 6.1.16, and of the same machine running DA 6.1.19 (142514)." defect closed guest additions VirtualBox 6.1.18 worksforme Arch ZFS Linux Linux
