Known issues with Eucalyptus 1.6

• Squeeze debian package installation/upgrade can exhibit odd behavior due to underlying dependencies changing often (For example, availability of the Xen hypervisor package by default). If upgrading, please see Upgrade Procedure for instructions on how to back up your existing data (users, images, keys, etc.) before attempting the upgrade.

• If the front end runs out of disk space, it can deadlock and hang. Make sure that you always have enough disk space for the front end logs, buckets and volumes.

• If the permissions on the buckets storage root directory for Walrus are too restrictive and "EUCA_USER" (typically eucalyptus) is unable to create files, Walrus may not respond to requests. Please make sure that the eucalyptus user can write to the buckets (and volumes) root directory.

• The file axis2c.log contains errors: [error] rampart_handler_util.c(241) [rampart][rampart_handler_utils] 0 parameter is not set. [error] error.c(94) OXS ERROR [x509.c:284 in openssl_x509_get_subject_key_identifier] oxs defualt error , The extenension index of NID_subject_key_identifier is not valid These errors are benign and can be ignored.

• On some distros (CentOS), if you are using Eucalyptus with Xen, you might see an error like, [EUCAERROR ] libvirt: cannot read directory /etc/xen: Permission denied (code=38)

This does not affect the node and can be ignored.

• If you see the following error in nc.log [EUCAERROR ] libvirt: POST operation failed: xend_post: error from xen daemon: (xend.err 'Error creating domain: (4, \'Out of memory\', "xc_dom_boot_mem_init: can\'t allocate low memory for domain\n")') (code=11)

you are likely running a 64-bit image on a 32-bit installation. Please check your image.

• If nc.log indicates failed to create swap.

you are likely out of disk space. Check that you have enough space under "INSTANCE_PATH" on the NC.

• Changing networking modes and most networking configuration options requires a CC (and sometimes a CLC) restart ($EUCALYPTUS/etc/init.d/eucalyptus-cc cleanrestart).

• EC2 command-line tools fail with Server: An error was discovered processing the <wsse:Security> header. (WSSecurityEngine: Invalid timestamp The security semantics of message have expired) Solution: Ensure that the clocks on the client and server machines are synchronized. This is not a Eucalyptus bug, but a consequence of the security policy enforced by the ec2 command-line tools.

• Difference from EC2: a Eucalyptus instance can only be a member of one security group.
