** Summary changed:
- virt-manager create new "Unable to read from monitor" after increasing memory
size
+ virt-manager create new VM fails with "Unable to read from monitor" after
increasing memory size
** Description changed:
- If you increase the memory to 2048 while creating a new virtual machine
- in virt-manager the action fails.
+ Creating a new virtual machine fails in virt-manager if you increase the
+ memory (RAM) to 2048.
Why is this important
- ==================
- The error message printed does not give a hint why the VM creation failed.

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-12.10-desktop-amd64.iso", then choose "Linux", "Ubuntu 12.10 Quantal"
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.
Workaround
===========
- Do not change the memory size above 2048 MB in wizard.
- Modify memory size later.
+ Do not change the memory size in the create vm wizard.
+ Change memory size in the virtual machine properties later.
Kind regards,
Thorsten
