The LSize shows the upper limit for the volume's size, and the Data% shows how much of that is used. When you clone a VM (lets say an appVM), you'll notice another private volume is created and shows the same figures as the volume it originates from. But looking at pool00 (the overall container for our VM volumes), the Data% barely changes if at all. $ qvm-clone windows windows2 windows2: Cloning private volume windows2: Cloning root volume $ sudo pvs PV VG Fmt Attr PSize PFree /dev/sdb2 qubes_dom0 lvm2 a-- 58.76g 8.71g Qubes manager gives the disk of the clone VM as 0 before I run it: https://imgur.com/NGAjTxg Though afterward it gets the same disk size as the original: https://imgur.com/hCGUVqs So again I assume that's the virtual space allocated to the clone rather than the actual space. Yes. The Linux storage options won't show a volume that grows from nothing and has a size equal to the delta from the parent volume. This is because the Thin LVM and Btrfs objects are not really hierarchical, and this can be a good thing because it usually means fewer demands on you attention... there is less 'care and feeding' necessary with the Linux options. But you do have to keep an eye on your overall free space, of course. If you really need to know the delta size between two related volumes, there may be a utility out there that scans the volume metadata and shows you. My guess is you would most likely find it for Btrfs, and it would be described as a tool related to deduplication (or 'dedup'). And that brings me to another point: On Btrfs if you have two related files (.img volumes) but suspect they have diverged too much over time, you can tell Btrfs to perform deduplication to find new commonalities and reduce the overall space used.

Re: [qubes-users] AEM boot = GPU hang, no graphics display

As noted on qubes-issues, I had to remove "iommu=no-igfx" from Xen options to get graphics working. Another side-effect that AEM/tboot has, unfortunately, is that sleep/suspend no longer works (now it causes an unintended reboot when entering sleep). But its been a long time since this combination worked. Chris -- You received this message because you are subscribed to the Google Groups "qubes-users" group.

Re: [qubes-users] mr. tasket's vpn new SMTP errors timeout in thunderbird

The proxy firewall config doesn't have any impediments to email. There has probably been a surge in attacks lately against email services, who sometimes block the SMTP port from VPN IP addresses; this is usually done to deter spammers or stem a rise in attacks. Even VPN providers may choose to block port 465 so they stay in the good graces of service providers. -- Chris Laprise, tas...@posteo.net https://github.com/tasket https://twitter.com/ttaskett PGP: BEE2 20C5 356E 764A 73EB 4AB3 1DC4 D106 F07F 1886 -- You received this message because you are subscribed to the Google Groups "qubes-users" group.
