comment How to force systemd enter in emergency mode?
The "in use" error could also happen if there are sub-mounts under the btrfs mount point. Looking at man systemd.mount and man systemd, systemd might be handling that automatically.

apparently NFS3 can do TCP. (I think the difference in NFS4 is that _only_ TCP is supported)

comment Cannot install Ubuntu on EFI/GPT scheme
Sorry, I missed "This message appeared when I tried in the BIOS to change SATA from ISRT to AHCI". That sounds like an really bad idea on an installed system. At least, the other way round would be, and I bet the docs don't recommend this direction either. Hmm.

comment Cannot install Ubuntu on EFI/GPT scheme
But gdisk shouldn't assume to look at the 'final sectors'; it should find the "backup header" (heh) based on the offsets in the main GPT. How could you get that gdisk error without corruption (possibly corruption caused by fakeraid)?

comment Cannot install Ubuntu on EFI/GPT scheme
Good idea, and thanks for sharing your experience. In this case the`gdisk` error is coming from sda, not a dm/md device. So I guess the idea is not that the final sectors are 'missing', but they come 'too early' because the end of the device has been reserved for a RAID trailer.

Yep, that's right about ping.

comment it takes too long to connect to ssh server
If you haven't already, I would also double-check one or two normal lookups on the VMs. Since it works correctly on the host, I don't think it's a problem with your ISP (or your local router). I'd say both your VMs are fine, it's VirtualBox that's broken (especially as they provide specific packages for each revision of Ubuntu). Whether that's a misconfiguration on your specific system, or a bug that needs fixing in VirtualBox? I don't know, sorry. Presumably there's a VirtualBox community forum you can sign up and get flamed at :-).

One suspicion is that VirtualBox almost certainly has an integrated DNS server, and it could be buggy somehow. Another would be an old buggy DNS relay software (I've seen some badness on outdated DNSMasq) is running on your home router.

2. Note that dig does not refer to /etc/hosts. If /etc/resolv.conf lists the same nameserver on both VMs, I would expect dig -x 10.0.2.2 to timeout on the debian VM as well. And the same would apply to the host system i.e. the one VirtualBox is running on.

comment it takes too long to connect to ssh server
Ah, I missed two things. 1. the check SSH is running is not expected to cause a delay even if the reverse mapping is missing. The DNS should immediately return an empty answer, and the client would not retry the query. Your problem isn't like the particular ISP incompetence I referred to in the answer, if that's what your phrasing meant.

comment it takes too long to connect to ssh server
Ok. The hosts file is used for reverse lookups as well as normal lookups, so that probably is what causes the difference. Are you saying the VMs are using an ISP DNS server, i.e. if you look /etc/resolv.conf it does not show an IP address in one of your own network ranges like 10.0.2.2 ? If so, then yes, it is ISP incompetence. (And by implication they're unlikely to be competent to fix it on advice of a single consumer. So you get to work around it yourself. In which case, e.g. installing unbound as a recursive resolver on the host machine would be a good idea in general).

comment it takes too long to connect to ssh server
It sounds to me like "UseDNS no" on the server should avoid the delay. (I often notice the delay when using ssh locally in the absence of working DNS). Is that the case or not?

comment Kernel panic when passing noatime in bootargs
I see the documentation you linked is also dated 2003. So you could make that argument. If this was a common problem I'd blame the kernel for being inconsistent instead. In practice... if you keep reading the thread it suggests that using an initrd/initramfs to mount the rootfs instead could work around it, and initramfs is the common case nowadays (at least for non-embedded). My search also brought up specific complaints that this problem happened when booting without an initramfs. Which I should have mentioned if I wasn't being lazy. Eg bugzilla.kernel.org/show_bug.cgi?id=61601
