GrubConf - The valid GRUB configuration¶
Combiner for Red Hat Grub v1 Grub v2, and BLS information.
This combiner uses the parsers:
insights.parsers.grub_conf.Grub1Config
,
insights.parsers.grub_conf.Grub1EFIConfig
,
insights.parsers.grub_conf.Grub2Config
,
insights.parsers.grub_conf.Grub2EFIConfig
, and
insights.parsers.grub_conf.BootLoaderEntries
.
insights.parsers.grub_env.GrubEnv
.
It determines which parser was used by checking one of the following
parsers/combiners:
insights.parsers.installed_rpms.InstalledRpms
,
insights.parsers.cmdline.CmdLine
,
insights.parsers.ls_sys_firmware.LsSysFirmware
, and
-
class
insights.combiners.grub_conf.
BootLoaderEntries
(grub_bles, grubenv, sys_firmware)[source]¶ Bases:
object
Combine all
insights.parsers.grub_conf.BootLoaderEntries
parsers into one Combiner-
version
¶ The version of the GRUB configuration, 1 or 2
Type: int
-
is_efi
¶ If the host is boot with EFI
Type: bool
-
entries
¶ List of all boot entries in GRUB configuration.
Type: list
-
boot_entries
¶ List of all boot entries which only contains the name and cmdline.
Type: list
-
kernel_initrds
¶ Dict of the kernel and initrd files referenced in GRUB configuration files
Type: dict
-
is_kdump_iommu_enabled
¶ If any kernel entry contains “intel_iommu=on”
Type: bool
Raises: SkipComponent
-- when no any BootLoaderEntries Parsers.-
-
class
insights.combiners.grub_conf.
GrubConf
(grub1, grub2, grub1_efi, grub2_efi, grub_bles, rpms, cmdline, sys_firmware)[source]¶ Bases:
object
Process Grub configuration v1, v2, and BLS based on which type is passed in.
-
version
¶ returns 1 or 2, version of the GRUB configuration
Type: int
-
is_efi
¶ returns True if the host is boot with EFI
Type: bool
-
kernel_initrds
¶ returns a dict of the kernel and initrd files referenced in GRUB configuration files
Type: dict
-
is_kdump_iommu_enabled
¶ returns True if any kernel entry contains “intel_iommu=on”
Type: bool
Raises: Exception
-- when cannot find any valid grub configuration.Examples
>>> type(grub_conf) <class 'insights.combiners.grub_conf.GrubConf'> >>> grub_conf.version 2 >>> grub_conf.is_efi False >>> grub_conf.kernel_initrds {'grub_initrds': ['/initramfs-3.10.0-327.36.3.el7.x86_64.img'], 'grub_kernels': ['/vmlinuz-3.10.0-327.36.3.el7.x86_64']} >>> grub_conf.is_kdump_iommu_enabled False >>> grub_conf.get_grub_cmdlines('') []
-
get_grub_cmdlines
(search_text=None)[source]¶ Get the boot entries in which cmdline contains the search_text, return all the boot entries by default.
Parameters: search_text (str) -- keyword to find in the cmdline, being set to None by default. Returns: A list of insights.parsers.grub_conf.BootEntry
objects fo each boot entry in which the cmdline contains the search_text. When search_text is None, returns the objects of all of the boot entries.
