description |
If you increase the memory to 2048 while creating a new virtual machine in virt-manager the action fails.
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/share/virt-manager/virtManager/asyncjob.py", line 45, in cb_wrapper
callback(asyncjob, *args, **kwargs)
File "/usr/share/virt-manager/virtManager/create.py", line 1909, in do_install
guest.start_install(False, meter=meter)
File "/usr/lib/python2.7/dist-packages/virtinst/Guest.py", line 1236, in start_install

File "/usr/lib/python2.7/dist-packages/virtinst/Guest.py", line 1304, in _create_guest
dom = self.conn.createLinux(start_xml or final_xml, 0)
File "/usr/lib/python2.7/dist-packages/libvirt.py", line 2166, in createLinux
if ret is None:raise libvirtError('virDomainCreateLinux() failed', conn=self)
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.
Kind regards,
Thorsten

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.

Failure reported to the user does not help to solve the issue.
