Portable cloud. Update statusu.

Napísané , autor:

Tak zas som sa hral z Portable Cloudom a posunul sa ďalej. Narazil so na dva problémy. Jeden zo sudo právami a druhý z nastavením šablóny pre vm. To prvé je nedostatok na strane správcu balíčkov. To druhé vyzerá ako problém na strane použitého storage.

Sudo problém: /etc/sudoers.d/opennebula-node treba upraviť. Pridaný riadok je označený hrubo.

 # OpenNebula sudoers file
 #
 # Allow member of cloud group (ie. oneadmin)
 # to call /usr/sbin/xm and /usr/sbin/xentop
 # without password.
 #
 Defaults:%cloud !requiretty
 %cloud    ALL=(ALL) NOPASSWD: /usr/sbin/xm *
 %cloud    ALL=(ALL) NOPASSWD: /usr/sbin/xentop *
 %cloud    ALL=(ALL) NOPASSWD: /sbin/ebtables *

 %cloud    ALL=(ALL) NOPASSWD: /usr/bin/ovs-vsctl *
 %cloud    ALL=(ALL) NOPASSWD: /usr/bin/ovs-ofctl *

Problém z datastorom. Vyzerá to tak že GlusterFS nepodporuje vypnutie cache. Tak treba upraviť riadok v template:  /etc/one/vmm_exec/vmm_exec_kvm.conf

# Default configuration attributes for the KVM driver
# (all domains will use these values as defaults).  These values can
# be overridden in each VM template. Valid atributes are:
#  - emulator
#  - os [kernel,initrd,boot,root,kernel_cmd,arch]
#  - vcpu
#  - features [acpi, pae]
#  - disk [driver, cache, io]
#  - nic  [filter, model]
#  - raw

#EMULATOR = /usr/libexec/qemu-kvm

#VCPU = 1

OS       = [ boot = "hd", arch = "i686" ]
FEATURES = [ PAE = "no", ACPI = "yes" ]

DISK     = [ driver = "raw" ]

#NIC     = [ filter = "clean-traffic", model="virtio" ]
#RAW     = "<devices><serial type="pty"><source path="/dev/pts/5"/><target port="0"/></serial><console type="pty" tty="/dev/pts/5"><source path="/dev/pts/5"/><target port="0"/></console></devices>"

Nakoniec ešte jeden prídavok. Aby v logoch ubudlo varovaní odporúčam nainštalovať pm-utils

apt-get install pm-utils

Všetky tieto zmeny budú v priebehu zajtrajška premietnuté aj do stránok projektu.
