Subject: [PATCH] appliance: Use -cpu max.
|
||||
|
||||
QEMU has a newish feature (from about 2017 / qemu 2.9) called -cpu max
|
||||
which is supposed to select the best CPU, ideal for libguestfs.
|
||||
|
||||
After this change, on x86-64:
|
||||
|
||||
KVM TCG
|
||||
|
||||
Direct -cpu max -cpu max
|
||||
(non-libvirt)
|
||||
|
||||
Libvirt <cpu mode="host-passthrough"> <cpu mode="host-model">
|
||||
<model fallback="allow"/> <model fallback="allow"/>
|
||||
</cpu> </cpu>

Subject: [PATCH] mlstdutils/std_utils.ml: Fix for OCaml 4.12.
|
||||
|
||||
We were using a default function from somewhere called "compare"
|
||||
instead of the actual function (Pervasives.compare / Stdlib.compare).
|
||||
Since the wrong default function was used it had a different type from
|
||||
what we expected:
|
||||
|
||||
File "std_utils.ml", line 312, characters 36-37:
|
||||
312 | | (y, y') :: _ when cmp x y = 0 -> y'
|
||||
^
|
||||
Error: This expression has type int but an expression was expected of type
