[Bug 1029889] Re: LVM Based KVM VM taking 100% CPU on first start and hangs.
Sorry for not responding for so long. Just to be sure, your symptoms are exactly the same as in the Description - kvm hangs (no response to network or the vnc console) and takes 100% cpu? Yes, the symptoms are exactly the same. Unfortunately, based on your .xml file it looks like you're not using an LVM backed VM. I wonder if we should pursue this in a separate bug. Would you mind opening a new bug? I've experienced the exact same bug (or at least the exact same symptoms) both with LVM and qcow2 images. If you feel that LVM is a sufficiently differentiating factor then I'm happy to file a new bug. I've found that two out of three servers with 12.04 are affected by this bug. That means that brand new images built on these machines exhibit this bug. However, I am still able to build images on the third server which work as expected on any of the three servers. I don't know what to make of that, since the machines should be close to identical in setup (and are certainly identical from a hardware perspective). -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to qemu-kvm in Ubuntu. https://bugs.launchpad.net/bugs/1029889 Title: LVM Based KVM VM taking 100% CPU on first start and hangs.

[Bug 875440] Re: Cannot authenticate with saslauthd and mysql
Solved-Works I really hope this helps some people on here but I've found a solution that does NOT require uninstalling packages or installing anything that's not in the stock repos for precise 12.04 for use in saslauthd(cyrus), mysql, postfix scenario. The gist of the problem seems to be syntax changes and the fact that if used in postfix (with chroot environment), a missing link in /var/run to the chroot of /var/spool/postfix/var/run/saslauthd. If postfix is chrooted (and it probably is) /etc/default/saslauthd OPTIONS=-c -m /var/spool/postfix/var/run/saslauthd -r (needed the -r option, that puts the name and domain together, short for realm, without that it will send the user as george not geo...@example.org /etc/pam.d/smtp auth required pam_mysql.so user=mail passwd=yourdbpassword host=127.0.0.1 db=maildb table=users usercolumn=id passwdcolumn=clear crypt=0 account sufficient pam_mysql.so user=mail passwd=yourdbpassword host=127.0.0.1 db=maildb table=users usercolumn=id passwdcolumn=clear crypt=0 (this file needed the appropriate references to the database and table names and since I used clear passwords, I needed to change crypt=1 to crypt=0. (and the passwdcolumn from crypt to clear) I did this so the clear passwords would read all the password. Using crypt in the mysql table, it would only recognize the first 8 characters and ignore the rest. And here's where the real changes took place, in the syntax. /etc/postfix/sasl/smtpd.conf file need the changed syntax (alot) and relevant sql query info. NOTE: I did NOT need the pam mech_list option that I thought before. pwcheck_method: saslauthd mech_list: plain login cram-md5 digest-md5 log_level: 7 #Remove this line when done allow_plaintext: true auxprop_plugin: sql sql_engine: mysql sql_hostnames: 127.0.0.1 sql_user: mail sql_passwd: yourdbpasswd sql_database: maildb sql_select: select clear from users where id='%u@%r' and enabled = 1 (note the use of the field clear, you probably want crypt if using flurdy's how-to. /etc/postfix/master.cf submission inet n - - - - smtpd # -o syslog_name=postfix/submission # -o smtpd_tls_security_level=encrypt -o smtpd_sasl_auth_enable=yes -o smtpd_client_restrictions=permit_sasl_authenticated,reject /etc/postfix/main.cf # SASL smtpd_sasl_auth_enable = yes # If your potential clients use Outlook Express or other older clients # this needs to be set to yes broken_sasl_auth_clients = no smtpd_sasl_security_options = noanonymous # also add # Add permit_sasl_authenticated to you existing smtpd_sender_restrictions # Add permit_sasl_authenticated to you existing smtpd_recipient_restrictions Fixed the sasl path problem by writing a script as such to run at boot as I didn't want to try and figure out what the hell the deal was with the path, how it starts, what starts it, what names it, sasl is a pain in the ass! #!/bin/bash sleep 5 ln -s /var/spool/postfix/var/run/saslauthd /var/run/saslauthd /etc/init.d/saslauthd restart /etc/init.d/postfix restart That did it!!
