First thing I'm seeing at the top of the error log is that a system vm
cannot communicate over port 8250 to 10.100.0.10 which looks to be a
host. If the secondary storage vm cannot communicate with the host, it
cannot copy the snapshot from the host and move it to secondary
storage. That would explain why the vm starts to perform a snapshot and
then fail when it attempts to move it to the secondary storage.
I would investigate that networking issue first.

Hello all, me again. After fixing some issues, I've narrowed my KVM
snapshot issues down to some more specific errors. Here is a log of both
the management server and the agent log from the hypervisor the snapshot is
supposed to run on.

Not captured by those logs: I try taking a snapshot by using the snapshot
button in the instance. Whether the instance is running or not, it tells me
that KVM snapshots aren't enabled. The snapshots are enabled, I checked and
double checked in global settings.
After that, I went to Storage and selected the root volume for the
instance. From there, I can click the snapshot volume button and the
snapshot *does in fact* begin, however, after an unknown amount of time
(takes too long for me to actually know how long) it fails with an internal
error (3). I have several snapshots of the process and result, but I feel
like there shouldn't be attachments to list messages, so if you want them I
can send them to you. The logs coincide with the screenshots. After
failing, the snapshot is stuck with the status of "CreatedOnPrimary" and
can only be deleted.
My question is, what am I doing wrong? Are there any steps that I have
missed? How do other users have KVM snapshots set up?
Thanks in advance!
