XE vm-export compress options

[DustinB]

What are the two options for compression from the cli? Obviously I can use xe vm-export vm=uuid filename=path compress=true but within XO there are two options, how can I call those via the cli?

Have you tried compress=zstd?

When xe vm-export is run with compress=zstd, does the xe vm-import command need to be told that compression was used, or does the xe vm-import command see that zstd was used?

[Danp]

@Strebor AFAICS, xe vm-import doesn't offer an option to specify the compression level, so I am going to assume that it handles this automatically.

It's handled automatically.

THANKS! That is a great addition!

Well, to be fair, it's pretty logical: you only have the control on compression format when you export. When you import, you already have your file in a previously selected format. So yeah, it's up to you to detect it, and that's what we do when we added zstd compression

Haha, I lost belief in 'logical' many years ago. What I think is logical and what others think is logical, often is very different
So, I still think it's great, cause it takes one command out of my CLI VM import pipe line
