Tengo un error cuando trato de cambiar memory allocation en una máquina virtual ya definida.
Uso CentOS 5.6_x86_64bits. y el kernel es Linux 2.6.18-238.9.1.el5 #1 SMP Tue Apr 12 18:10:13 EDT 2011.
El error que me da es el siguiente:
Traceback (most recent call last):
File "/usr/share/virt-manager/virtManager/details.py", line 1459, in config_memory_apply
self.vm.set_max_memory(maxmem.value * 1024)
File "/usr/share/virt-manager/virtManager/domain.py", line 1280, in set_max_memory
self.vm.setMaxMemory(memory)
File "/usr/lib64/python2.4/site-packages/libvirt.py", line 627, in setMaxMemory
if ret == -1: raise libvirtError ('virDomainSetMaxMemory() failed', dom=self)
libvirtError: this function is not supported by the connection driver: virDomainSetMaxMemory
There are any patch or solution for this ?
