Bug Description
Creating a new virtual machine fails in virt-manager if you increase the memory (RAM) to 2048.
Qemu log file says:
*** qemu: at most 2047 MB RAM can be simulated
So virt-manager should not allow assigning more than 2047 MB of RAM in this setup.
Why is this important
=======
The error message printed does not give a hint why the VM creation failed.
Complete error message
=======
Unable to complete install: 'Unable to read from monitor: Connection reset by peer'
Traceback (most recent call last):

File "/usr/lib/
dom = self.conn.
File "/usr/lib/
if ret is None:raise libvirtError(
libvirtError: Unable to read from monitor: Connection reset by peer
Steps to reproduce
==================
1. start virt-manager
2. wait
3. press NEW button
4. Step #1: enter name for new virtual machine e.g. "ubu1210", leave default "local install media"
5. Step #2: choose iso image from local drive e.g. "ubuntu-
6. Step #3: set Memory (RAM) to "2048"
7. Step #4: disk size and location do not matter, choose anything
8. Step #5: just press FINISH button
VM creation fails after the disk image had been created.
Failure reported to the user does not help to solve the issue.
Kind regards,
