setelah di lihat dari errornya, ternayata masalahnya karena “Failed to allocate the network(s), not rescheduling.” itu menyebabkan virtual port dari instance ke host compute tidak terbentuk, sehingga muncul error seperti itu. untuk mengatasi masalah tersebut sebernarnya caranya cukup simple dan mudah untuk dijalankan (ya iyalah namanya juga simple :P, becanda :D).

-------------- ------------- | controller | ------------------------>| compute01 | -------------- ------------- | | ------------- ------------------------------->| compute02 | ------------- |
jadi saya punya 1 controller dan 2 compute
edit pada semua node (controller dan kedua compute)
|
[root@controller ~(keystone_admin)]# vim /etc/nova/nova.conf vif_plugging_is_fatal = False vif_plugging_timeout = 0 |
ubah nilainya seperti diatas, kalo udah tingal restart servicenya aja pada semua node
|
[root@controller ~(keystone_admin)]# systemctl restart openstack-nova-* [root@controller ~(keystone_admin)]# systemctl status openstack-nova-* |
untuk testing, coba buat instance lagi, harusnya berhasil, kalo masih gagal coba liat log nya lagi 😀
semoga dapat membantu 😀
