i worry about performance of quantum use subnet in one dhcp & l3 agent work for it(more dhcp & l3 just for backup)
if quantum have any solution to performance about quantum dhcp & l3 (may be one compute node have dhcp & l3 agent work for local VMs) Thanks, Tommy 2013/3/20 Martinx - ジェ�`ムズ <thiagocmarti...@gmail.com> > User "quantum" running `python /usr/bin/quantum-dhcp-agent'... > > > On 19 March 2013 22:55, gong yong sheng <gong...@linux.vnet.ibm.com>wrote: > >> that depends what user is running the dhcp agent. >> >> On 03/20/2013 09:52 AM, Martinx - ジェ�`ムズ wrote: >> >> My /etc/sudoers.d/nova_sudoers contains: >> >> -- >> Defaults:nova !requiretty >> >> nova ALL = (root) NOPASSWD: /usr/bin/nova-rootwrap >> -- >> >> Do I need to change it? >> >> Tks! >> Thiago >> >> >> On 19 March 2013 22:46, gong yong sheng <gong...@linux.vnet.ibm.com>wrote: >> >>> It seems be about sudo. >>> to create one sudo file under /etc/sudoers.d >>> mine is: nova_sudoers: >>> Defaults:gongysh !requiretty >>> gongysh ALL = (ALL) NOPASSWD: ALL >>> >>> >>> On 03/20/2013 09:37 AM, Martinx - ジェ�`ムズ wrote: >>> >>> Hi! >>> >>> I just rollback to the default namespace options, my Instance now get >>> its IP without problem. >>> >>> But, the message from my first e-mail on this thread, still persist... >>> >>> I tried to enable quantum metadata proxy stuff but, nothing changes... >>> >>> The following error keeps rolling at >>> my /var/log/quantum/dhcp-agent.log: >>> >>> --- >>> ... >>> Command: ['sudo', 'ip', 'netns', 'exec', >>> 'qdhcp-21a39c11-03fd-4e2e-b7a0-94eee95f5f91', 'quantum-ns-metadata-proxy', >>> '--pid_file=/var/lib/quantum/external/pids/21a39c11-03fd-4e2e-b7a0-94eee95f5f91.pid', >>> '--network_id=21a39c11-03fd-4e2e-b7a0-94eee95f5f91', >>> '--state_path=/var/lib/quantum', '--metadata_port=80', '--debug', >>> '--verbose', >>> '--log-file=quantum-ns-metadata-proxy21a39c11-03fd-4e2e-b7a0-94eee95f5f91.log', >>> '--log-dir=/var/log/quantum'] >>> Exit code: 1 >>> Stdout: '' >>> Stderr: 'sudo: no tty present and no askpass program specified\nSorry, >>> try again.\nsudo: no tty present and no askpass program specified\nSorry, >>> try again.\nsudo: no tty present and no askpass program specified\nSorry, >>> try again.\nsudo: 3 incorrect password attempts\n' >>> --- >>> >>> I tried everything I could...
