[fedora-virt] unable to boot rhel5 guest with 3.19.7-200.fc21.x86_64

[Reartes Guillermo]

Hi,

Since a couple of days i noticed that i cannot boot a rhel5 guest on
my F21 machine.
Today i was able to test it properly by rebooting a couble of times.
There seems to
be some issue with kernel 3.19.7-200.fc21.x86_64

Did anybody experienced something similar?

HOST: FEDORA: 21
      CPU: AMD FX(tm)-6100

* With KERNEL: 3.19.7-200.fc21.x86_64
  GUEST
   * RHEL5: 5.11
   * KERNEL: 2.6.18-404-el5 (also tried: 2.6.18-400.1.1.el5, 2.6.18-398.el5 )

   * RESULT: Guest HANGS, with 100% vcpu usage after grub (no nash...
kernel alive, etc)

   * If i try booting from the RHEL5 5.11 release iso image (cdrom),
it works...


* With KERNEL: 3.19.5-200.fc21.x86_64
  GUEST
   * RHEL5: 5.11
   * KERNEL: 2.6.18-404-el5 (also tried: 2.6.18-400.1.1.el5, 2.6.18-398.el5 )

   * RESULT: Guest boots normally. No known issues. (also booting the
iso also works)


Thanks in advance.
