However, you can encrypt non-essential datasets on a boot pool (that is, if com.datto:encryption is "active" AND the bootfs dataset is not encrypted, you can still boot from it). This is what my tests showed too (on 12.2 with OpenZFS from ports).

FreeBSD 13.0 terrible performance in KVM
Hello List, I hope some other folks out there running FreeBSD on KVM as well. I set up a base VM while doing so I noticed that the disk operations are very slow. Many times I edit a file in vim or try to run a command there is a huge lag. I use UFS as the root filesystem. To have something to compare it with I have tested it against an OpenBSD 6.6 VM on the same host, same hardware. both have 1 vCPU and 1GB of ram, 20GB virtual disk (they are exactly on the same physical disk no raid or anything to have a fair comparison). Here is an example simple file search time for a non-existent file: FreeBSD 13 time find / -name cacert.pem real 0m30.656s user 0m0.516s sys 0m3.938s Second run even worse real 2m38.618s user 0m0.711s sys 0m6.882s While on the OpenBSD VM I get time find / -name cacert.pem real 0m2.258s user 0m0.290s sys 0m1.970s The amount of data is about the same on both systems but I would not consider this a "slight" performance degradation. If the base system is so slow then imagine putting Apache and other servers on top of it. Did anyone run into this? Unless there is a definitive solution I will opt out to using other BSD variants. ___ freebsd-stable@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org"

It’s a huge and common problem that has been going on for years. I also had the same problem with XenServer. You can search bugzilla for „KVM“ bugs, as well as the forums. Apparently, it was mostly fixed for VMWare, but fixing for KVM is apparently very difficult. Even more so as there are many different versions of KVM around that all behave differently, depending on how you configure the virtual hardware (of which there are endless variations and permutations on how you attach with virtual devices to which virtual PCI-bus etc.pp.). It’s also likely fixed on AWS (but I do not use that, so I hardly care). E.g. when I created a KVM VM on my local workstation at work, it performed identically (more or less) to e.g. a CentOS VM. However, if I create a VM on our on-premise Openstack cloud, it achieves maybe 10% or 20% of the disk-IO-speed of a CentOS VM with the same volume type. There’s some work going on in some differentials, but I haven’t had the time to try. The problem is IMHO that most of the paid developers (for FreeBSD) these days either use it on bare metal (hello Netflix, EMC, Netapp, Netgate et.al.) or use it inside VMWare, where the main pain-points seem to have been fixed. Or they even use FreeBSD’s own hypervisor (bhyve). It’s a tragedy IMO and it totally rules out FreeBSD here around for almost all future use-cases (that are almost certainly moving to Openstack in the future). ___ freebsd-stable@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org"
Re: FreeBSD 13.0 terrible performance in KVM
We have over 50 FreeBSD VM on KVM for years, several Proxmox (5x,6x) and Centos (6.x,7.x) servers, and never experienced performance problem like this. Your example on fresh new 13 VM: # time -p find / -name cacert.pem real 0.28 user 0.00 sys 0.13 12.2 our syslog server: # time -p find / -name cacert.pem real 4.12 user 0.21 sys 3.77 Our hardware are Supermicro, IBM and Fujitsu servers with Xeon CPU-s, some with HW raid, others with ZFS as datastore, previous we had several IBM x3650 ... Everything was ok. No big difference between Linux and FreeBSD guests. We use Linux as guests only if we have to. ___ freebsd-stable@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org"

Despite the documentation, "etcupdate extract" handles -D destdir (and its contribution to the default workdir)

iPhone tethering not working
I tried to connect my iPhone SE2 (iOS 13.7) to FreeBSD 12.2-stable. After loaded the kernel module if_ipheth, I connected my phone. > ugen0.2: at usbus0 Then I typed usbconfig -u 0 -a 2 set_config 3 > ipeth0 on uhub6 > Ipeth0: on usbus0 Then I chose to trust the computer, but nothing happened. My computer still can’t get to the internet. This is ifconfig ue0 output: > ue0: flags=8843 metric 0 mtu 1500 > ether > nd6 options=29 I tried dhclient ue0, but got no reply from iPhone.
